The hierarchy of engagement | Sarah Tavel (Benchmark, Greylock, Pinterest)

0:00

I think a lot of people think about markets  almost like these bodies of water, it's like it's this big body of water that we're going after.

0:06

I  actually think that the most interesting markets, you have to think of them like currents where  you're there's something happening in the market that's creating this current where you can have  a plank of wood that you've put on the river and it's going to pull you forward.

0:26

Versus a market  that doesn't really have that momentum to it, you're going to have to build something really  big and fancy to make any progress.

0:32

That's why we care less about market size because really,  what you're looking for when you're looking at a market, are what are the dynamics of change,  what's the current and momentum that's going to pull the company and make the job easier for the  founders to actually build something that endures.

Today, my guest is Sarah Tavel.

0:56

Sarah is a partner  at Benchmark, one of the most preeminent venture capital funds in the world, where she focuses on  investing in consumer and marketplace startups.

1:07

Prior to Benchmark, Sarah was the first product  manager at Pinterest.

1:07

And though I normally have a policy against VCs on the podcast, as you'll see,  Sarah thinks very much like a product and growth leader.

1:18

And I always learn a ton talking to Sarah  about startups and marketplaces.

1:18

We also learn in our conversation, she used to play rugby and was  apparently one of the best tacklers in her league.

1:28

In our conversation, we unpack two of Sarah's  killer frameworks for building a startup.

1:28

One, the hierarchy of engagement, which is an  incredibly useful lens for trying to figure out how to grow and scale your consumer startup.

1:38

And then, the hierarchy of marketplaces, which is an incredibly useful guide for helping you build  your marketplace startup.

1:43

If you're building a consumer startup or a marketplace, this episode  is for you.

1:48

We get really nerdy and really deep, just the way I like it.

1:53

With that, I bring you  Sarah Tavel, after a short word from our sponsor.

Sarah, thank you so much for being  here and welcome to the podcast.

3:12

Super excited to be here.

3:13

So you may or may not know this, but actually,  normally have a policy of no VCs on the podcast.

3:18

But you're a very special VC because you're  a former product manager.

3:18

Many people don't know you were the first product manager  at Pinterest.

3:23

To me, you still think like a product manager so I'm very excited to  break my rule and have you on the podcast.

3:31

Thank you for the exception.

3:33

What I want to do with our time together  is dig into two frameworks that you've developed and use with founders that you  work with to help them build successful companies.

3:42

One is focused around customer  businesses, and one marketplace businesses.

3:49

Let's just start with the first framework.

3:49

I  think you call it the Hierarchy of Engagement.

3:54

Just to start, could you maybe just share a  broad overview of this framework?

3:54

And also, just where it emerged from, where  you came up with this concept? Sure.

4:01

I think one thing you'll notice about me  is that I have an allergic reaction to vanity metrics, what people talk about as vanity metrics.

4:12

When I made the transition from Pinterest, where I was leading product for the discovery team, so  I was responsible for all the discovery surfaces on Pinterest.

4:25

The home feed, the search, the  recommendations, a couple other teams.

4:25

Ultimately, what those teams were about was about engagement,  increasing engagement of Pinterest.

4:31

It was helping people, when they were on Pinterest, find  something that they loved enough that they wanted to pin it to one of their boards.

4:44

When I started to meet with all these really talented consumer founders building consumer  social products, this was during a time when everybody was getting excited about growth  hacking.

4:57

What you would see is that you would see all these founders coming in, and they  all had these up and to the right graphs, whether it was sign-ups, or downloads,  or MAUs.

5:09

It felt to me like it wasn't obvious that those metrics that they were  all getting very attached, and focused on, and showing in these presentations was the wrong  thing to focus on.

5:25

It didn't get to the heart of whether they were on the path to building enduring  consumer social product.

5:32

They were missing, at the core, the criticality of engagement.

5:40

I just started to feel this and it became like a pebble in my shoe.

5:47

I started just to go  through that process that you've gone through many times before of writing and distilling it,  and that's where I came up with this hierarchy.

6:03

What you realize when you look at social products  is that they're almost is this action which I call the core action of that product that  forms the foundation of the product.

6:09

When a user completes this action, it's clear that they  both understand the utility of the product, they understand what that product is all about, and  it's an action that, if they perform the action, they're very likely to come back.

6:27

So for Facebook,  the obvious action is friending, in the beginning days.

6:34

For Pinterest, it's pinning.

6:34

I don't  know if you're an Evernote user.

6:34

For Evernote, it's writing a note.

6:40

When you perform that action,  that means you're an engaged user.

6:40

Of course, there's a lot of other actions that you have  to do.

6:46

You can follow people on Pinterest, you comment on Facebook.

6:50

But the end of the day,  if you're not doing that action, you're not really a user to the product.

6:56

That's why the MAU thing  doesn't really mean anything.

6:56

It's really looking at, I think, of users completing the core  action.

7:03

You can look at this as a cohort, weekly, daily, whatever the right cadence is.

7:09

But that's the foundation, that's level one.

7:16

Basically, there's some definition of an active  user that a consumer business basically needs to define, and essential figure out what is that  action they're taking that makes them an active user versus just opening up the app, or whatever  it is.

7:27

For Snapchat, it might be sending a snap. That's right.

7:34

For What's App, it might be  sending a message. Okay, cool. Yes. Yes.

7:36

By the way, this action, it's very  important to pick the right action.

7:36

You want to make sure it's an action that scales  to enough users.

7:43

You want to think about, "If I think about my product roadmap and  optimize for it, what do we end up doing?"

7:56

Just to give you a more concrete example,  actually in the early days of Pinterest, we weren't sure what it was.

8:00

We had all  these things we were measuring.

8:00

We were measuring follows, we were measuring clicking  through, liking something, pinning obviously, time on site.

8:12

We would do these experiments  and you would get all this different data where some things would go up, some things  would go down.

8:18

What were we optimizing for?

8:23

There's something that's really, really important  about having that clarity of this is the action that is most important for our product.

8:30

All  things, our NUX has to lead to this.

8:30

If a user isn't doing this, then there's something missing  from their experience of the product.

8:36

It's super important to get real clarity and know exactly the  one that you're going to be picking to go forward.

8:49

One more question along these lines.

8:49

How do you think about this milestone versus the  activation milestone for a new user?

8:56

Do you find they're often the same?

8:56

Getting your user to that aha moment- Yes. Versus ongoing? Right.

9:01

Part of it is how do you measure the  success of your NUX, of the activation?

9:01

To me, it is are you taking those new users  and helping them understand the mental model of your product well enough that  they start completing the core action. Awesome.

9:19

There was a NUCs once that we played with  at Pinterest where we didn't even teach people what pinning was.

9:23

It was their  feed magically appeared and it was a real ...

9:28

That was an example of okay, we  have to help people understand that they are here to discover something  and save it to their board.

9:36

Just in case people don't know what NUX is, new user experience.

9:38

It's just an  acronym for new user experience. Thank you. Yes. Okay.

9:41

Maybe one more just foundational  thing that I think we maybe skipped is what's the best way to think about using this  framework?

9:44

Is this essentially where you should focus your energy, on which elements  of your product you should be driving, which metrics to focus on?

9:53

Is that a  simple way to think about ...

9:53

Basically, we've talked about layer one and there's  three layers.

9:56

What's the best way to think about, as you're talking through this  framework, of how to apply it and use it?

10:02

In a way, you have to think holistically  when you're building these consumer products, when you're designing it.

10:06

But I think it's very  important, once you get the product out and you're starting to optimize, to start thinking through  each of the levels.

10:11

That's just very focusing, to help a founder understand, "What are the levers  that I really have to be focusing on to improve?" Awesome.

10:26

I want to come back to how  to apply it, in maybe some examples, after we go through the three  levels so I'll turn it back to you. Perfect.

10:32

Let's say you're building your product  and you're starting to see that you have users completing the core action.

10:40

Then, the next  challenge you have, and I've seen this many times before, is that then you have to figure out how  to get those users to stick around.

10:46

You want to retain those users.

10:51

Obviously, if they do the core  action once or twice, and then they run out of steam, you're going to be in a really challenged  position to build something that endures.

11:03

The test for me, of whether you're building  a product that has the ingredients to create a retentive product on a micro level, just at  the user level, is that the product should get better the more you use it, and you'll have more  to lose by leaving it.

11:15

I'll give you a couple examples there, a couple of my favorite products. Obviously, Pinterest.

11:22

One of the features that I worked on when I was at Pinterest and we shipped  was this idea of a picked for you feed.

11:30

The idea was every time you pinned something to a board, we  would take that information that the user gave us and use it to create recommendations in their home  feed.

11:45

It may have been the first algorithmic feed that was in a social product because, suddenly  your home feed wasn't just things and people that you followed.

11:57

The truth is, people weren't  really following other people on Pinterest so we needed a way to make the experience get  better the more you used it, so we started to do these recommendations in your home feed.

12:07

It was this experience that, the more you pinned, the more personalized your home feed got for  you.

12:12

Then, the more you pinned, you also had more to lose by leaving Pinterest because, all  of a sudden, you had all your favorite books, articles you wanted to remember, the recipes  that you were planning on cooking one day, the holiday planning that you were doing.

12:30

So you wouldn't abandon Pinterest because Pinterest was this repository for these  different expressions of your identity, or these different bookmarks that you wanted to back  to. That was this idea.

12:39

It's very important that the core action is the thing that you use as the  product to make the experience better over time.

12:52

Evernote, another example.

12:52

I don't  know if you're an Evernote user. No.

12:57

I tried it once and it was way too  complicated, and I gave up quickly.

13:01

People still laugh at me  for being an Evernote user. Oh, wow. I'm a lifetime user. Wow.

13:09

It's one of those things that I take all  my notes in Evernote.

13:09

I dump documents in Evernote.

13:15

What I means is that, the more  I use it ...

13:15

Now I know that I can do a search in my Evernote and I'm going to  find the document I'm looking for.

13:21

Now, I can never leave Evernote. It has  everything.

13:26

I have thousands and thousands of documents in Evernote.

13:30

That's  a product that's incredibly retentive.

13:37

Unless someone builds a great exporter,  and then there goes that piece of friction.

13:41

People keep telling me I need to  move on to Notion or something else, but not yet.

13:44

I will remain a dinosaur here. Wow.

13:48

I love that that's an example  of someone can break that barrier and make it less retentive, by  making it easier to get off. Yes.

13:55

It's interesting growth strategy, basically. Yes. Yeah, it's very true.

13:57

Let's say,  now, you have a product, it's growing, more people are completing the core action.

14:04

When  they complete that core action, the product gets more retentive for them.

14:10

It gets better the  more they use it, they have more to lose by leaving it.

14:14

Then, your tall task, and this is the  hardest thing to overcome, is how do you make the product self-perpetuating?

14:25

This is where I love  to think of every time a user users your product, let's say they're clicking on the mouse or they're  tapping on their phone, I love to think of it as this kinetic energy that they're putting into  your product.

14:41

You're taking that energy, and your job with a great product, is to take that energy  and, as much as possible, convert it back to the experience that they're having with your product.

14:53

Now, the biggest thing that you can do is a network effect.

14:58

The more I pin something on  Pinterest, the better the experience for every user on Pinterest.

15:06

Every time I add a pin to a  board, I'm creating a new edge in Pinterest Graph, that Pinterest then uses to create recommendations  and enrich their understanding of all those objects on Pinterest.

15:19

The network effect is the  strongest thing that you can do.

15:19

And obviously, if you have that, which all social products have  to in some way, you have to spend time, as much as possible, just maximizing where that shows up,  fine-tuning it, removing friction so that it's a flywheel that spins faster and faster.

15:39

But, there's other loops too, that you have to identify and then maximize.

15:45

These are the growth  and re-engagement loops.

15:45

These are classic loops, you talk about these a lot, they exist in  marketplaces and social products.

15:53

How do you get it so that, as your users use the  product, they want to share it with other people?

16:02

They create metadata that you can then  use for SEO.

16:02

You have collaborative experiences that pull other people in.

16:10

There's all different  things you can do here.

16:10

And then, there's also things that you can do to re-engage a user.

16:15

As an example, in the early days of Pinterest, if you pinned something, you're pinning something  that you found on Pinterest that somebody else pinned.

16:27

So we would send a push notification,  "Hey, Lenny, Sarah just pinned your pin to her art board."

16:34

Now, if you were a dormant user at  that point, it's been a couple weeks since you'd used Pinterest, that notification might pull you  back into Pinterest and be like, "Hey, I wonder what other pins Sarah has on her art board."

16:46

It's a great re-engagement loop where Pinterest doesn't have to do anything there intentional.

16:53

The user is creating the action that drives the outcome that Pinterest wants in that example.

16:59

Now, as much as I love Evernote, this is a place where Evernote obviously falls down.

17:07

There's no  loops that they can take advantage of, that when I use the product, I make it better for you.

17:15

There's  no loop where, when I use the product, I want to pull you into the product.

17:20

They tried at some  point, to do collaborative journals, it doesn't work.

17:25

That's a place where, because of that,  Evernote had to spend money to acquire users, they tapped out.

17:33

They missed that level three.

17:33

There's other examples I could speak to, of companies that weren't able to transcend to  level three, that you wouldn't otherwise think.

17:41

I think of companies like Houseparty and Clubhouse.

17:47

What was interesting about both of those products is that you would think that the more users that  came into Clubhouse or Houseparty, the faster the flywheel should spin.

18:02

But the challenge was  that they relied on push notifications.

18:02

I don't know if you had this experience, but let's take  Houseparty as an example.

18:08

You started to follow a lot of people on Houseparty, and then all  of a sudden, your push notifications just got overwhelming.

18:20

Because it was a realtime product,  that you had to use push noti cations to know the moment to join the product, but when you had  so many push notifications because the more people you followed, the more notifications you  had, you just get to this point where you start ignoring them.

18:38

It becomes this thing where, even  though the flywheel should be spinning faster, it starts breaking down.

18:45

That's the  real tricky nuance in this level three.

18:52

I think people hearing this are going to  be like, "Okay, getting people to use your product more often, increase retention, make it  viral basically," it's stuff they already know.

19:02

But I think what's powerful about this is this  is just a lens, a clarifying lens on what is most important.

19:06

There's so many things you can be  focusing on to increase your product's success and help it grow.

19:13

What I love here is just, "Here's  the three most important things, and then here's the levels."

19:18

They build on each other.

19:18

If you  want to increase retention, get people to do the core action more often.

19:24

If you want to help it  grow, focus on helping it spread, self-perpetuate. Yeah, I know. That's absolutely right.

19:30

The  importance of it is I can't emphasize enough how important focus is when you're building  these companies. It's so hard.

19:37

There really isn't a playbook.

19:43

Every company, the ones that  succeed have to be fundamentally different from anything that was before it.

19:50

But there are  these first principles of the ingredients that they all share, and you can use  those ingredients to really focus you when you're going through the inevitable  growth curve and wanting to know, "Well, how do we maximize this moment?

20:07

How do we  really focus on the things that will set us most up for success?"

20:12

That's where I think a  framework like this can be really clarifying.

20:17

There's a lot of depth behind each of these  things that you're being modest about.

20:17

One is, with the top of this pyramid  of making it self-perpetuating, the reason that's really important is for a  consumer app to work well most of the time, it has to be able to spread really cheaply.

20:29

The cost of acquisition needs to be very low, unless you somehow figure out some paid ad  strategy where you can make money with paid ads, which is very rare.

20:40

So maybe speak to why  that's so important to a consumer product. Yeah.

20:45

What are you trying to build with a consumer  product?

20:45

You're not trying to build something niche.

20:50

You want to build something that can be  a mass-market, hundreds of millions of users, billions of users.

20:57

It would take considerable  capital to do that with marketing.

20:57

There's one example that we have so far, which is  TikTok, of spending more than $1 billion, once they figured out actually the first two  levels in order to grow.

21:12

They didn't actually put user acquisition spend behind TikTok until they  had a product that was retentive, and then they know that they really wanted to maximize that.

21:26

But  every other social product has grown organically.

21:37

They've been able to do so because they've figured  out how to maximize these loops.

21:37

Even TikTok got to millions over users before they spent all  the capital to acquire those remaining users.

21:51

I didn't know that number.

21:51

TikTok  spent $1 billion on paid ads- Yes.

21:55

To get to where they are today? Yes. Holy moly. Yes.

21:58

I knew it was many millions, but I  didn't realize it was $1 billion. Yes.

22:04

That just shows you how hard it  is to break in and become a new social network, essentially, or a new social app. It is hard.

22:10

And then, at the same time  though, we do see exceptions to it where I still feel like consumers are hungry for  new experiences.

22:16

We've seen a couple over the last few years that have gone into  tens of millions of users.

22:22

Nothing that has really created the experience that's  sticky enough to pull minutes away from, really TikTok and Instagram, which just  are these dominant forces right now.

22:42

Your message also reminded me of a recent guest post on my newsletter about this app  Saturn, I don't know if you read it. Oh, I didn't.

22:49

But I know of the app,  and it's just an awesome founder. Yeah.

22:53

It was really interesting.

22:53

They had a  really interesting insight about, first of all, very few apps ever make it to the top of the  app store that break through what's already there.

22:59

The ones that do almost always spend a  few days there and then, are gone because it's a one shot thing.

23:04

What they basically talked  about is many apps have this viral K-factor, where they spread like crazy, everyone starts  using them, everyone's in there.

23:09

But then the opposite happens very quickly, too, where  if a few people miss using it a few days, you go in there and it's, "Oh, nothing's  happening here anymore," and it quickly crumbles.

23:23

Clubhouse essentially went through  this, BeReal started go through this, where people stopped posting and then, "All  right, forget this. Everyone's gone."

23:27

Most apps have this destructive K-factor that kicks in,  the same way it kicked in to get it to spread. Yes.

23:35

As people say, when something grows really  quickly, it also can collapse really quickly. Yeah. Tough.

23:43

I guess along those lines, is there anything you've seen or learned ...

23:45

The idea of this framework is to avoid that, essentially.

23:50

But I guess, is there  anything comes to mind to avoid that?

23:55

One other thing that I've seen that runs  into a challenge, and I find it runs into a challenge particularly with level  two, is anonymity.

24:00

Anonymity is something where ...

24:07

Pseudo-anonymity and anonymity are  very different concepts.

24:07

With pseudo-anonymity, we have it on Twitter, you have it on Reddit.

24:14

You  have a persistent identity that you're creating, and that identity then can have  accruing benefits, mounting loss.

24:25

My pseudo-anonymous account on Twitter that  just flames other VCs ... I'm just kidding. This is breaking news.

24:35

I'm not funny enough to make something like  that.

24:35

But for the people who do have it, they get accruing benefits because they get people  to follow them.

24:42

And that's the mounting loss too, where they've grown their identity  on a platform even though it's a pseudo-anonymous identity.

24:54

The challenge when you  have pure anonymity is that you don't have that accruing benefit or mounting loss that happens.

25:02

I don't know if you ever played with Secret, but it's similar to TikTok or something like  that.

25:07

These are the types of experiences where, over time ...

25:14

The network effect doesn't work  because the anonymity creates the conditions for bad behavior, so that starts to  pull down the community.

25:23

And then, it is also the experience where you'd  use a product and you can delete, and then come back three months later, and  because of the anonymity aspect of it, your experience isn't any different.

25:39

I find anonymity,  people keep trying it, and super talented founders keep hitting their head against that wall  because it has the very early fun growth, but it just continues to be a product that isn't  able to persist without some persistent identity.

26:04

I'm going to pull on this thread of just  ways to increase retention.

26:04

Basically, this is one of the things, maybe the main thing  you're telling people to help increase retention, make it so that it's really hard to leave.

26:13

Before  we get there, just to make it clear, is this framework mostly for social consumer products,  or do you generalize it to consumer products?

26:24

I think it's consumer products in general. Okay.

26:28

But it makes the most sense for consumer social. Okay, got it. It works for Evernote.

26:34

Evernote  isn't a consumer social product. Awesome.

26:39

Okay, so it's most  helpful for if you're the social, your friends are in it sort of product? Right.

26:45

You have the chance  of level three with social. Right, awesome. Okay.

26:48

On this thread of  retention, it's a thing that I speak about often, everyone always talks about.

26:54

The most important  thing you got to get right is get retention to a good place because if you can't retain  people, nothing's going to work anyway.

27:02

So just to spend a little more time here, is  there anything else you recommend to founders to help them with increasing retention and  getting to a healthy place with retention?

27:13

Number one is actually measuring it.

27:13

I can't tell you how many times I suggest to a founder to track cohorts and  that's a new thing.

27:18

Just being really, really clear and intellectually honest on  looking at cohorts I think is number one.

27:34

Okay, maybe just describe that briefly, and then we'll link to an article  that I have about how to do that. Perfect.

27:38

These are the moments when I should  probably turn the mic over to you, to talk about- Nope, you're in the hot seat. [inaudible 00:27:46].

27:46

A cohort, what I always  like to look at is weekly cohorts for these products.

27:53

You look at them in two ways.

27:53

Which is one, for each vintage of cohorts, you're looking at a group of people who  signed up in a given week, and that's one. ...

27:59

like a group of people who signed up in  a given week and that's one cohort.

27:59

You look at it both on an active user basis, like are  those people continuing to come back to the product?

28:11

And I particularly love to look at  that on a weekly active user completing the core action pieces of like, are users completing  the core action?

28:18

How is that changing overtime for each of the cohorts?

28:25

And then also, looking  at activity level within those cohorts.

28:25

And so, what you love to see is the kind of classic  smile graph where, as the network grows and users start to use the product more and  more, you start to see that, overtime, they actually become more retained in the product  as opposed to kind of the classic leaky bucket where the cohort just keeps on dwindling down.

28:50

And until you reach a point with your cohorts where there is a plateau, you have more work to  do on figuring out the retention of your users.

29:04

The second thing is just focus.

29:04

So I can't  tell you how how many times also you'll meet a founder and they will...

29:10

There was one  example I saw, it was a kind of a dating app, friend making app, and he was growing it via  TikTok, which is not geographically constrained at all.

29:24

And so, he's growing the user numbers,  but without focusing on a specific geography, it's gonna be really difficult to make that  type of product a high retention product.

29:39

Coming back to the framework, which  layer do you find most often is the one founders maybe are under-investing  in/maybe the most important to focus on if you had to pick one of these, or is  it super dependent on your situation?

29:57

What I often feel is that, a lot of times, product  founders, consumer founders, see where they want to get to, they compare themselves to the  full expression of a product that you see with other products, ROBLOX, Instagram, TikTok,  whatever it may be, and they want to get there.

30:19

But what that ends up meaning when the when a  new user signs up is that there's too much in the beginning to to take in and understand, and  you don't then have a very focused product that gets the user to the thing that you most  want them to do.

30:36

And that's actually part of the importance of understanding level  one, what your core action is, is that you want to make sure that when a user comes to  your product, signs up for the first time, doesn't have necessarily a lot of contacts on  what the product is itself, that they see the thing that they're supposed to do and you get them  to do it.

31:00

And a lot of times, in the beginning, there are just so many other things that  a product might have that you're defusing that attention that they would otherwise have  had on the on the thing that's most important.

31:19

And so, I feel that that's the first  mistake, and it's kind of natural that it would be the first mistake, but maybe  the largest mistake that I see people make.

31:31

Essentially, not getting  the activation moment right, not focusing enough on getting people  to that aha moment as people describe, and then again, that repeating  again and again as a core action. Yes.

31:43

To close the loop on this sort of discussion,  could you just share again a few examples of core actions/activation moments, just to make this  fresh again in people's minds?

31:49

And then also, just whatever you could share about  helping people decide what that is.

31:54

I know it's a difficult thing to do well, but  any advice for how to find that activation?

32:03

I mean, I'll tell you the exercise that we did  at Pinterest because as I mentioned before, it wasn't obvious to us in the beginning of  Pinterest like were we a social network?

32:08

Like should we optimize for the follow graph?

32:14

But  you have to remember, Pinterest, this was 2011, you had Twitter growing like crazy, Instagram  was growing.

32:20

Those were both asymmetrical follow graphs that they were creating, right?

32:27

And so,  it wasn't clear at the time whether Pinterest was actually just creating a new follow graph, but  that was about things instead of what Twitter was or what Instagram was.

32:40

And so, it wasn't obvious.

32:40

And what happened actually is that there was two efforts that I think of as like kind of bottoms-up  and top-down that helped really clarify that, actually, pinning something was the  core action, it was going to be our North Star.

32:59

We called it weekly active pinners.

32:59

And the two things were, there's always this like bottoms-up analysis that you do, which is,  we looked at every action that you could do on Pinterest, so we had liking, following, clicking  through, time on site, pinning, repinning.

33:15

And we looked at, first of all, what percentage of users  complete those actions?

33:25

And if you do that action in a week, what's your propensity to come back  the following week?

33:32

And we basically ranked that.

33:37

And what we saw was that if you pinned something,  repinned something, which is finding something on Pinterest, I'm using those synonymously,  or click through, you had an incredibly high probability that you would come back.

33:50

So if  someone's pinning something, they're coming back to Pinterest the next week with a super  high, more than 90% probability at the time.

34:02

And then there's like the top-down way  of thinking about it, which is, well, what is Pinterest for?

34:08

And if a user does come to  Pinterest and they never add something to a board, do they really understand what Pinterest is?

34:15

And  yes, clicking through makes you want to save it.

34:21

The click through is valuable, you want save it,  so clicking through is obviously really important.

34:27

But at the end of the day, if they don't like that  pin enough that they want to save it themselves to their board, then we haven't done our job.

34:32

And so, we did this kind of top down, bottoms up analysis to make it very clear that when we  launch an experiment or launch a new feature, if the probability, if the percentage of people  that pin something doesn't go up, or the number of pins for that cohort doesn't go up, that  experiment is not a a successful experiment. Awesome.

34:58

There's a post I'll link to in the  show notes where there's actually a guide to doing this regression analysis on how  to figure out your activation milestone. Amazing.

35:07

Basically, what is most causal of  retention as you're describing.

35:07

And I love this example from Pinterest. Any other just examples?

35:11

Again, you shared a few at the beginning of just examples  of great activation milestones/core user actions.

35:20

I'll tell you one other one that I thought was  super interesting, which is that when I initially published this post, I had assumed wrongly that  YouTube's core action was watching a video.

35:24

And then Shishir Mehrotra, who was the kind of CPO  of YouTube, he reached out to me and he said, "That's what it was in the early days, but we  started to realize that it wasn't actually our core action.

35:49

And we did a lot of analysis  on YouTube and what we realized was that subscribing was the core action on YouTube."

35:55

And it makes so much sense when he said it, right?

36:01

You're a creator, you're  uploading content onto YouTube, there are a lot of other places at that time  that you could have uploaded that content to, but you care about YouTube because that's where  you're growing your audience, right?

36:12

And so, the more people that subscribe to your content  on YouTube, the more you have the accruing benefits and mounting loss of using YouTube.

36:22

And so, that was super important on the creator side, which, one of the funny things that  will bridge to our next conversation is that all social products are really marketplaces,  right?

36:33

YouTube is a marketplace.

36:33

You have the creators uploading content and the viewers  who are watching it, supply and demand.

36:45

And so then, the subscribe button is also very  interesting because then from the demand side, the viewer, why would I come back to  YouTube consistently versus, again, all the other places I could spend time on  if it weren't for me having found creators for whom their content really resonates with me  so much so that I subscribe to their content?

37:10

And so, I loved that example because it  showed a little bit the evolution that can happen with these companies, but then also,  just the beauty of like you know you've got something really right with the core action  when it's helping both sides of your network. Awesome example.

37:26

And I think it's  also a good reminder people change these things.

37:29

"You come up with your best  bet.

37:29

Okay, we tried this for six months, maybe let's try something else.

37:33

We've learned something new." Exactly.

37:37

I'm also going to link to this post I wrote  around finding your North Star metric, which was like such a multimedia conversation  with just links for all these topics to go deeper.

37:45

Essentially, I figured out the  North Star metric for, I don't know, 30 companies.

37:50

And I feel like the North  Star metric of a company ends up often being this core user action.

37:54

So like Pinterest,  it sounds like those WAPs, weekly active pinners. Yeah. Pinners, yeah.

38:01

And YouTube is subscribers.

38:02

In the beginning we called it weekly  active repinners and war because we felt like we were at war, so it was good.

38:08

And then, it became peacetime maybe. Yes, exactly. Awesome.

38:11

So maybe just to close the thread on this  framework, can you just briefly summarize who this is most helpful for and just how they could  apply it if they're maybe not growing as fast as they want or they're just getting started  as a founder building a consumer product?

38:29

Yeah, I think about consumer  founders, product founders, product leaders in these companies that  are thinking through the road map.

38:32

What is the most important things that they  need to prioritize, the big rocks, for the immediate short-term?

38:43

And the framework  then provides a lens on what to prioritize.

38:50

And we'll link to the whole framework  for people that want to go deeper. Awesome.

38:54

Okay, so let's move on to your second framework  that you called the hierarchy of marketplaces.

38:59

And first of all, I want to give a shout-out to  Mike Williams, who's the founder of Everything Marketplaces, who gave me a bunch of good  question suggestions to ask as we do this.

39:07

Wonderful, now I'm nervous. He's Mr. Marketplace. Yes.

39:11

Okay, so let's start with the same question,  just what's kind of the broad way to think about what this framework is and who it's  for?

39:15

And then, where did it come from?

39:18

It's a framework or hierarchy that is for  marketplace founders.

39:18

It could actually be B2BC or B2C, or marketplace product leaders that  are like either getting started or scaling their marketplace and helping kind of prioritize  and focus on the things that most matter.

39:42

And it came out of a similar reaction, a very  similar parallel to what I was experiencing, meaning, all these consumer social founders.

39:50

Like  they would talk about MAUs and I just felt like it didn't get to the heart of whether they were  building enduring value.

39:56

And I actually started to realize that GMV was very similar.

40:03

GMV,  it's a metric that it seems like...

40:03

Of course, you can't build a marketplace without growing  GMV in the same way that you can't build a social product without growing MAUs.

40:17

But if you focus,  if the race that you think you're running is to grow MAUs or to grow GMV, you're not actually  going to run the right race. It can take you...

40:31

And actually, with marketplace, very  interestingly, it can take you in the wrong direction.

40:37

So what would happen is I  would meet all these founders and everybody got fixated on this milestone of $1,000,000 of  GMV. Right.

40:43

And I think a lot of people started to feel like if you could hit $1,000,000 of  annualized GMV, it means you're ready for your Series A.

40:55

But it's kind of self-evident  that not all GMV is created equal, right?

41:02

So imagine a food delivery company 10 years  ago.

41:02

You could have $1,000,000 of GMV by focusing on LA, or $1,000,000 of GMV by focusing  on Boston, or you could have $1,000,000 of GMV by having $500,000 here, $200,000 here, like  spreading it out.

41:20

And I would meet so many founders who would say, " Oh, well, I thought  we had to prove out that the value proposition resonated in these other cities and so, that's  why we're diffusing our focus."

41:34

But what they what I would always feel is like they were just  making their job so much harder by doing that.

41:46

The other way you could think of it is like  if you're trying to get to $1,000,000 of GMV as quickly as possible, you're actually  motivated to go after a really big market, right?

41:56

It's a lot easier to get to $1,000,000  of GMV when you're skimming the cream on this big ocean of a market, then to be very, very  focused on a smaller market.

42:02

And getting to $1,000,000 of GMV in a constrained market is  a lot harder, takes longer, but it's actually the path to building something that endures.

42:14

And so, I was having the same conversation again and again and I just felt like I needed  to crystallize it or synthesize it in a way that would be easier to communicate,  and that's what led to this hierarchy. Awesome. Okay, cool.

42:30

So you've touched on a number of the important elements  of this hierarchy, so let's dive in. Okay.

42:35

There's probably a couple  core insights, but the first one that I think about with this hierarchy is  that when you're building a marketplace, you actually have to start from the  goal and work backwards from there. Now, what's the goal?

42:50

Marketplaces, I mean,  you have so much incredible content on this, they're just incredibly difficult to build.

42:57

You're basically building two companies at the same time, right?

43:03

You have the product  and go-to-market org for the demand side, the product and go-to-market org for the supply  side.

43:07

And somehow, you have to make these two line up so that they serve each other's needs.

43:12

It's an incredibly difficult dance.

43:12

And yeah, it's one of the hardest types of companies in  the software world that I think you can build.

43:29

And you do it because you think about the the  full expression of these models and you think about companies like Airbnb or Amazon or eBay  or Google, where once you have scale and have very dominant market share, you have a product  that just is the best place without question of fulfilling this need.

43:52

And they end up being very  profitable cash-flowing businesses.

43:52

And you see that, and that's the business that you want to  build, that's why you're going through all the hardship of building a marketplace, getting the  marketplace off the ground to get to that place.

44:09

And there's kind of very clear analysis.

44:09

I  published it in the hierarchy.

44:09

I have this incredible graph that I remember seeing when I  board observer for this online classified company called OLX led by Fabrice Grinda.

44:23

And it kind  of shows that the more dominant a marketplace is relative to the number two in its space,  the more profitable that business is.

44:32

And so, it's just like a very clear like you don't  want to be...

44:38

Obviously, when you're building a marketplace, you don't want to be in the  middle of the pack, but even being number one but just barely number one doesn't give you  any of the benefits of a marketplace model, you're fighting for each incremental point of  market share.

44:52

It's not clear to the supply side or the demand side that you're like the main place  to be.

44:57

And so, it only becomes really clear once you have that dominant market position where  you're just so much bigger than the number two And the only way to get to that place, to get  to that moment of real dominance where you have this winner take most dynamic is that you have to  tip your market, and that's the only scalable way to do that, and that's what level two is.

45:24

And so, how do you maximize your chance of tipping a market?

45:30

You have to focus on a really  constrained opportunity, and that is level one.

45:38

So that's kind of like the broad framing, which  is like a really important thing of how, when you're building a marketplace, you actually are  building towards that point of dominance.

45:45

And so, it's part of the reason why being really, really,  really focused in level one is so important. Awesome.

45:57

So you walked through  this backwards.

45:57

Just to summarize in case people didn't totally catch it,  basically, layer one is focus, layer two, tip the market, layer three, dominate the market. Exactly. Awesome.

46:09

So let's maybe start  with layer one of just focus- Let's do it. ...

46:13

which I think is the most counterintuitive  step for people building a marketplace where, as you said, normally, it's go big as fast  as possible, get as much GMV as possible, just make everyone happy as quickly as  you can.

46:22

And your advice is, essentially, do the opposite. Make it very...

46:27

You have this like great acronym of thimble that, I imagine, you'll talk about  that I love, I always think about. So yeah. Yeah.

46:34

And part of what's so hard about  this idea focus is I'm lucky to meet with just incredibly ambitious founders.

46:44

And the  hardest thing I think about building these marketplaces is that the ambition can often  feel like this sun, like the heat of the sun that's trying to warm everything up, and you're  going after this big market, warming the ocean.

47:04

And I think that, really, what the the best,  ambitious founders do is they focus that ambition like a laser beam on a small market, the  thimble.

47:11

And what you do is like you're getting that thimble, you're getting the product market  fit really, really right with this like small, constrained market.

47:23

And if you heat that up  really, really hot, then it expands from there.

47:29

And part of this is that we have to accept  a couple of points of scarcity.

47:29

One is that, you can't raise hundreds of millions  of dollars from the start, where we, especially today, live in a world where  there is a constraint around capital.

47:43

And so, you have to be able to take that capital in the  beginning and make the most out of it.

47:49

And the only way to do that is to be very, very focused.

47:53

And the second thing is that the constraint is the founder's attention.

47:59

And again, these things are  really, really difficult to to get off the ground, and the only way that you can do it is  by having myopic focus on a segment.

48:13

And the example that I always think about  was a very cool thing that we all got to see, which is when the food delivery wars  happened, where you had companies like DoorDash and Postmates and Uber Eats, and then,  the incumbents of Grubhub, take very different strategies.

48:33

I make comparisons to Postmates  and and DoorDash, both successful companies, but Postmates, from the very beginning, had very  big ambition and went after all the big cities.

48:53

They went after, not just restaurants,  but restaurants and Apple and retail, bicycle.

49:00

I remember, there were so many things  that they went after all at the same time.

49:06

And when you're playing that game, you're always  being compared to whatever other substitutes there are in the market, right.

49:12

And you're it and  that just when you have constraint of capital and attention you're you're spreading yourself  thin across a lot of different vectors of kind of preference for the customer and the seller.

49:25

DoorDash on the other hand, famously and very controversially went after the suburbs in the  beginning.

49:32

And the beautiful thing about the suburbs is that there is very little competition  because no one thought that you could do it economically.

49:43

And they probably weren't wrong  in the beginning, like DoorDash lost a lot of money in the beginning fulfilling delivery in  the suburbs, just because the delivery times, the driving was so long, but by going after a  market that other people weren't focused on, it let them get to a place where they were able to  really make the customers on both sides of their marketplace happy enough that they retained.

50:08

And this word happy I use, I should expand on it a little bit because the realization I had as  I reflected on this kind of feeling that GMV is really actually a vanity metric, it doesn't get  at the core of whether you're building enduring value.

50:33

It's like very clear and there's plenty of  examples I could give where there are companies that had incredible scale and still were disrupted  by a startup.

50:39

And it's because actually, customers don't care how big you are, they don't care how  many transactions you've accumulated.

50:48

What they care about is when they have a transaction  with you, how happy do you make them?

50:54

How much better is the experience that you provide  than any other substitute that they could use?

51:05

And if you do a good job, then they're gonna keep  coming back to you.

51:05

And so I call it happy GMV.

51:11

And that's actually the thing that I think you  as a founder or product leader have to focus on, which is, what do I think is going to be the  experience of a buyer or seller that leads them to retaining and tracking that as like  the happy path and therefore, the happy GMV. Amazing.

51:29

I love that concept, happy GMV.

51:29

You  also kind of extend this idea and I think you call it the minimum viable happiness is what  you want to create when you're building this marketplace, this symbol of water that  you're trying to boil into something incredible.

51:45

What's the minimum version of  that that creates really happy customers? That's right. Yes.

51:51

And kind of the  way to think of it is like, obviously, when you're a marketplace founder you know that  in order to build something endures, you're going to have to grow.

52:03

But you in the beginning, you're  you're doing all these things that don't scale, you're working on your product experience,  you're taking friction out of the transaction, and you want to get to a point where there's a  certain percentage of people that retain after having done a transaction.

52:22

And so, you're  kind of doing the work, doing the work, doing the work to get to that minimum threshold.

52:26

And that's when you know you get to kind of go to the next step of starting to figure out  the levers to really scale what you're doing. Awesome.

52:36

And again, it's easy to say, it's  difficult to do as a founder to tell them like, "You just need to get a small version of  this marketplace working, versus you go big really quickly."

52:46

And so, most of the  time, I think it's actually like location, basically start in a city if it's  location-oriented.

52:50

Or if it's all online, pick like one niche to focus on, like  Etsy was like, craft fair goods, right? Exactly.

53:02

And sometimes, as we saw with  Postmates, sometimes it's both, which is, geography and category.

53:10

Again, you have to assume  scarcity of your capital, of your attention, of your customers attention and so getting  complete clarity of what is the experience that you want to really nail, what's  that happy path you're optimizing for, constraining that in the beginning gives you  the option, the optionality to grow beyond that, but if you don't constrain, you just  won't be able to get there fast enough.

54:43

I want to talk about what it looks like when you you've got it working and it makes  sense to start expanding, but before I do, there's one kind of example I found in  my research which is really interesting, which is Thumbtack where they, from the beginning,  went national and across many categories.

54:57

And the founders admit maybe that wasn't the right idea.

55:05

It took them a long time to get to something that was really working.

55:10

But on the other hand, their  thinking was to create enough of a flywheel for people to keep coming back.

55:16

How often do you need  a plumber?

55:16

How often do you need a DJ?

55:16

So there's- I was just going to say that is the trickiness  with Thumbtacks model and it persists as the trickiness with their model, which is  that you don't have a high repeat use case there and so you have to...

55:34

One of  the really important things with building a marketplace is cornering the buy side, like  having a relationship with the buy side where they don't even think about where they're gonna  go, they come to you.

55:44

And if it's a plumber, you use that so infrequently that every time you  are going to look for a plumber, you're gonna start at Google, right?

55:58

You're not gonna assume,  "I'm gonna go to Thumbtack to find that because- I'm not going to assume I'm going to go  to Thumbtack to find that because you've already forgotten by that point.

56:03

And so you  need to have enough touch points with the consumer so that they'll have a relationship  with you and start to think of you as a place to go to.

56:13

And that's probably, that was the  trickiness with Thumbtack.

56:13

And by the way, when we talk through level two, that also level  two will articulate some more of that trickiness. Awesome.

56:26

By the way, I do use  Thumbtack.

56:26

It's implanted in my head of that's where to go  to find plumbers and stuff. That's great.

56:32

I mean those founders, I adore  Marco.

56:32

He is an incredible, incredible founder.

56:37

As a segue to layer two, what are signs  that you've done a good job at focusing and things are working?

56:45

You have this term  that I love of creating a white hot center, so maybe speak to that, or just  what tells you, it's like, "Cool, I think we've got this very focused  thimble.

56:52

How do we know it's time to go?"

56:57

Yeah, I think it's very much that  you see people retaining.

56:57

You just feel that where people are texting  you or emailing or whatever it is, that they've had a great experience and you  see them coming back.

57:09

And you're not going to make everybody happy. Let's all accept that.

57:15

But there's a core of users, a persona that you are able to make really happy.

57:23

That's when  you know that you're on the right track. Awesome.

57:28

It's essentially the very  fuzzy product market fit question. Yes, yeah.

57:32

And I'll link to a few posts I've  written that help people get there.

57:36

I guess is there anything you  want to add there like this?

57:39

The only thing I'll add, those two things  related I'll add.

57:39

I don't like NPS for this, and I have a whole blog post on this.

57:45

I like Sean Ellis's question of how disappointed would you be if this product  disappeared?

57:50

And I think it's if you have at least 40% of people respond that they'd  be very disappointed, then you're on the right track.

57:59

That's kind of the feeling that  should tell you you're on the right track. Awesome.

58:06

Okay, let's talk about layer  two around tipping the marketplace.

58:10

So layer two, I think, will actually  illuminate again the importance of that constrained focus for layer one.

58:15

You're  doing all these things that don't scale, that you've written so much about, Lenny, about  kick-starting, the marketplace, all those things that you can't just keep on doing forever.

58:26

Now, layer two, level two is about figuring out how to do things that do scale.

58:32

And  really, you're doing it in service of this kind of mythical moment of a tipping point.

58:39

And the tipping point is this idea that you often reach some kind of saturation point  in a market.

58:47

You've reached an experience, you've kept on working on the product experience,  you've taken a lot of friction out, and you keep on growing, growing, growing.

59:00

And you're  doing that in service of increasing happiness.

59:06

And this is a really important thing.

59:06

The  growth that you're doing, you should have a lot of clarity on your flywheel at this point,  and know that you're growing in service of accelerating your flywheel.

59:18

And people talk  about the flywheel as liquidity.

59:18

You could think of it as happiness, which is that the  more the flywheel spins, the more you're able to make both sides of your marketplace happy.

59:29

And what you're doing is you're growing into a greater percentage of your market.

59:36

And as you're  doing all these things again that don't scale, then you reach this moment where things start  to get a lot easier.

59:43

You've kind of pushed the boulder up the hill and it starts to slide down.

59:49

And what you notice first, I think, is you start to see it on a micro level where you might have  suppliers that start to tip to you or buyers that tip.

1:00:00

You might see your cohorts get a little  bit better.

1:00:00

You start to see some organic growth.

1:00:06

And let me give a story or an example of a company  that I got to see where the marketplace started to tip.

1:00:13

So we're investors in a company called  REKKI.

1:00:13

And REKKI is a marketplace for restaurants and their suppliers.

1:00:21

And it's, imagine in the  beginning, this kind of app that you could use.

1:00:27

It almost looked like WhatsApp, that a chef could  use instead of doing a voicemail at midnight when they're leaving the restaurant or typing something  into WhatsApp and texting it to their supplier, an email, whatever it is.

1:00:42

They could use this REKKI  app and it would make it a lot easier for them to do that.

1:00:48

And then of course the marketplace  elements is that then they'll be able to discover other suppliers on REKKI if they need them.

1:00:53

Now in the beginning, REKKI had to have their own sales force and they were going to London,  knocking on the doors of these restaurants, finding and cornering probably the chef in  the kitchen to show them the app, to get them to change to this new app called REKKI.

1:01:11

And  it's a very high cost of sales effort to have, as you might imagine.

1:01:19

But then what started  to happen is that every time they got a new chef onto REKKI, that order would then go to  the supplier that that restaurant normally ordered from.

1:01:30

And so instead of getting the  voicemail, the supplier would start to see a nice order form that was from the restaurant  and provided by REKKI, powered by REKKI.

1:01:43

And what would happen is that as  REKKI grew more and more in London, these suppliers started to get more and more  of their restaurants ordering via REKKI.

1:01:48

And then some of the early suppliers started to be  like, "Well, this is so much easier for me.

1:01:53

I would much rather get this order form from REKKI  than have to listen to an hour of voicemails from chefs with different accents and different ways of  ordering their food in the morning when I come in.

1:02:12

And so then the suppliers would  reach out to REKKI and be like, "Hey, here's a CSV of all of our customers.

1:02:16

Can you reach out to them and onboard them to REKKI because I'd much rather have my orders  come via REKKI than the way I'm getting them."

1:02:29

And so you go from this moment of the hard high  cost of sales, pounding the pavement, to getting a list on a silver platter of restaurants to  onboard.

1:02:39

And that's that feeling of tipping, where all of a sudden something goes from  being really freaking hard to so much easier.

1:02:52

It feels a lot like how people describe  finding product market fit.

1:02:52

Things start to feel like you're not pushing  anymore and it's just coming to you. Yes.

1:03:00

In your experience, is this tipping often just  happens as you become more successful in this thimble of a marketplace?

1:03:07

Or is it things  you have to do actively to tip to get to this place?

1:03:12

It sounds like in REKKI it was like  this feature they built of just recommending, "Hey, you should check out REKKI, and  maybe other suppliers would help you have an easier time if they're joining."

1:03:24

So  is it usually like it just happens with scale, or is there usually something you have  to change to create this tipping point?

1:03:31

I don't think Ronan predicted that that was  what was going to happen.

1:03:31

And you're constant, that kind of customer obsession, having  the relationships with the suppliers, having the relationship with the buyers, so that  you have your ear to the ground.

1:03:43

And when they start to lean in a little bit, you're there  to receive them.

1:03:48

And so I think this is very much part of what great marketplace founders  are able to do, is they're able to start to feel that there's something tipping in their  direction and then create momentum behind it.

1:04:09

And that's a lot of what this level two  is all about, which is that, I think, every marketplace has to figure out what  I call tipping loops.

1:04:15

And there's two types of tipping loops that work together  symbiotically to help a marketplace scale.

1:04:27

The first are the growth loops.

1:04:27

And so we  just talked about an example with REKKI.

1:04:33

There are many examples of this Hipcamp, another  marketplace I'm lucky to work with.

1:04:33

If you and I went camping on Hipcamp and I booked a tree house  on Hipcamp, and you are going to join me on it, I could then as part of my checkout flow,  essentially invite you to my reservation so that you could see the maps, the more information  about the tree house and any of the sites around it.

1:05:02

And so I'm the person that Hipcamp  acquired, but then I pull you into my experience and that's a great buyer to buyer growth loop.

1:05:09

There's classic seller to seller loops or buyer to seller, all these directions.

1:05:16

And then the great  marketplaces see those loops and they figure out ways to accelerate them.

1:05:22

So classic seller to  seller referrals.

1:05:22

Uber drivers would tell their friend, "Oh, you should start driving for Uber,  it's great."

1:05:32

But then Uber incentivize it with a referral bonus, and you started to see Uber  drivers literally writing blog posts about how much they loved driving for Uber because some of  them were making more money getting the referral bonus then actually driving.

1:05:51

And so you're trying  to find these growth loops and you maximize them. Awesome.

1:05:56

I'll link to a post that has a lot  of these insights from this work that I've done on marketplaces, but a few others that  are just interesting.

1:06:01

Basically you're trying to figure out how do you create a engine  that continues to drive supply and also drives demand.

1:06:09

So a fun example is when Etsy was  getting started, as you know, they went to craft fairs and pitched sellers, "Hey, sign up for  Etsy.

1:06:14

You could sell your stuff online."

1:06:14

And then all their sellers started telling all  their buyers, "Hey, buy my stuff on Etsy."

1:06:24

Etsy literally gave them business  cards.

1:06:24

So Etsy gave their sellers business cards that made them feel like, "Oh, I'm a real..."

1:06:32

Made them feel professional.

1:06:32

And the link on it was to their Etsy store. I love that.

1:06:39

One of the most magical growth  engines of marketplaces is when your supply brings on the demand.

1:06:45

So that's a really good  example.

1:06:45

Another one is DoorDash, where basically a restaurant signed up for DoorDash and then  they tell all the customers, "You want to order our food?

1:06:54

Go to DoorDash and order it."

1:06:54

And  so all the restaurants are telling everyone about DoorDash and then they become DoorDash  users and they order from other restaurants.

1:07:01

Yes, and it shows how creative DoorDash was  to both sides of the market in that example.

1:07:08

And then Faire is an awesome example too.

1:07:08

It sounds similar to REKKI as you described, where Faire is basically a B2B artisanal items  marketplace where boutique shops buy nice candles and blankets for their store to sell.

1:07:21

And  essentially they did what you described, where they signed on a store and they basically  told them, "All your vendors can join for free and not have to pay any fees if they sign  up for Faire, and it makes it easy for you to buy their stuff."

1:07:33

And then on the other side,  a candlemaker tells all the places they sell to, "Hey, you should use Faire.

1:07:40

It's so easy to  buy our stuff, and we can communicate through there."

1:07:43

And they can sign up without any fees.

1:07:43

So basically everyone just invites all their existing partners on Faire, and then everyone's  on Faire.

1:07:47

So yeah, there's a lot of ways to do it. I love it.

1:07:53

And so the second type of loop, and  again this loop works symbiotically with the growth loop, is what I call happiness loops.

1:07:58

And  I think of them almost as the kidneys for your marketplace as you grow.

1:08:05

The happiness loop, the  idea is you have a lot of new sellers coming in, and of course you have new buyers, but you  want to make sure that you are matching your buyers with the sellers that are  going to give them the best experience.

1:08:23

And so, normally in a consumer social product,  churn is heartbreaking.

1:08:23

Once a user churns, they're almost never going to come back.

1:08:32

And  with a consumer social product, you're trying to get to massive scale.

1:08:36

But when you're building  a marketplace, actually, there's a healthy amount of churn that you want on the supplier side  because there are just going to be suppliers who aren't going to create a great experience for  the buyer, and you can't do anything about that.

1:08:53

And so we've all had the Uber driver who you give  one star to.

1:08:53

That person you don't want on your marketplace getting matched with buyers.

1:08:59

And so  you're trying to then make sure that, as you grow, you have a natural mechanism in your marketplace  to reward the suppliers that you want to reward and to churn out the ones that you don't.

1:09:15

Of  course your job is to do your best to set all the sellers up for success, but it's an inevitability.

1:09:20

And so there's two great examples I think of in these happiness loops, which is around search  ranking, and then reputation.

1:09:27

Search ranking is just a very obvious one, which is, you're  trying to understand what creates a happy experience for the buy side, and then reward  the sellers that provide that experience.

1:09:46

So I think an interesting example that ended  up actually changing but still is illustrative, is that UberEats in the very beginning of their  journey, thought that their advantage in the market was going to be about having really fast  delivery, right?

1:10:01

Because they already had this network of drivers and so they thought that  that's where they were going to really lean in and have an edge over any competition.

1:10:11

And so  in the search ranking, they rewarded restaurants that prepared the food quickly, and so answered  the Uber Eats request, and then actually got the food out as fast as possible so that Uber Eats  became synonymous with the quickness by which you got the delivery.

1:10:31

And so that restaurant  that takes 40 minutes to prepare the food, they would get ranked low in the experience for Uber  Eats, even if the food was really, really great.

1:10:45

Okay, so we've been talking about  tipping of the marketplace.

1:10:45

Is there anything else there that you want to  share before we move on to the third layer?

1:10:53

Yeah, there's two other things that  come to mind.

1:10:53

One, just as a reminder, and then one as a caution.

1:10:59

So the reminder is  in order to tip a market, you have to reach a saturation point in that market.

1:11:09

You can't tip  a market before you've penetrated it to some saturation level.

1:11:16

And it goes back to level one  of why you want to focus on a constrained market.

1:11:23

Let's take growing a food delivery product  in Des Moines, Iowa versus LA or New York.

1:11:34

When you're growing in a small city  and you're focused on restaurants, you're going to be able to get to this tipping  point a lot faster and more efficiently than if you're going after a very big market.

1:11:44

And so  there's a real advantage to being able to prove out the playbook as quickly as possible and as  efficiently as possible before you move on to bigger challenges.

1:11:58

And so I think it underscores,  again, why it's so valuable in the beginning to focus on something that is constrained.

1:12:06

And again, Postmates focusing on San Francisco, the city.

1:12:13

DoorDash focusing initially on  the suburbs, much smaller opportunity, but one that they could really knock the cover  off the ball on. They had no competition.

1:12:24

They had a customer that was desperate for  attention, and so they could make them happy.

1:12:31

And that just sets you up for real success  to go from strength to the adjacent market.

1:12:38

The second thing that I'd say is, and this  is so important is that not all markets are susceptible to tipping, right?

1:12:46

We've all  experienced this, I'm sure Lenny, with the companies that you work with, the companies I  work with, where there are conditions of a market that make it vulnerable to tipping.

1:13:02

I have six  in my post just to name a couple classic ones.

1:13:11

The first obvious one is just concentration on the  supply side.

1:13:11

In order to be able to tip a market, you need suppliers to want to lean in on your  marketplace.

1:13:17

My partner, Bill Gurley talks about how great marketplaces create the new  incumbents.

1:13:25

So you basically have suppliers who aren't the incumbents.

1:13:33

The incumbents  aren't going to lean in on your marketplace, they're already fat and happy, but you want  to have these hungry suppliers who lean in.

1:13:44

But if there's already concentration  in your marketplace, in the ecosystem, the market that you're playing in, then  you're not going to have sellers lean in, and you're not going to be able to create a  flywheel that spins where the more sellers you bring on, the better the pricing or experiences  on the demand side because the sellers are happy and there's nobody that's hungry or fighting.

1:14:07

And so that's just a critical, critical point.

1:14:14

Bill Gurley and I actually had a little Twitter  debate once about supply versus demand and which one's more important.

1:14:18

And basically his pitch  was like, "All that really matters in the end, to build a successful marketplace, is  can you find the demand?

1:14:23

Can you bring the demand to your marketplace?"

1:14:27

It makes  all the sense in the world.

1:14:27

Everything in the end is, "Can you find customers?"

1:14:30

In the work I've done looking into marketplaces, what I find is the hardest thing to do,  to bring people to your marketplace, is to find the supply and bring it to people,  basically aggregate it.

1:14:40

And your point here is exactly right, is that basically the  value of your marketplace is to find this non-concentrated demand that's all over the  place and bring it together and make it easy to transact with.

1:14:55

So I think that is really  important, just to double down on this point, that what makes the marketplace valuable is  supply that is hard to find that you make easy to find and transact with.

1:15:08

And I feel like that's  almost the core of what makes marketplace work.

1:15:12

I think you're both right.

1:15:13

Yeah, I think we're both right. Right, right.

1:15:16

Because in the beginning, the only way you  get started with the marketplace, obviously, is you're bringing the supply online, and that's  what opens up the opportunity.

1:15:24

And the only way then for you to have a chance at tipping the  market is if there's enough fragmentation on the supply side to create a differentiated  experience for the demand side to care about your marketplace.

1:15:41

But the only way to build  long-term enduring value with a marketplace is to corner the demand side.

1:15:47

And so it's kind  of a little bit that evolution of a marketplace that ends up changing who you focus on.

1:15:51

And I don't know if you've experienced this in my experience with the marketplaces  that I work with, it's a constant like, "I have to focus more on the demand side right  now.

1:16:01

Okay, now we got to focus more on the supply side."

1:16:05

And it's just back to how difficult  these businesses are to build, especially when you have limited resources, that it's like  the forever battle of building a marketplace.

1:16:15

Yeah, especially if it's a geographically oriented marketplace like a DoorDash.

1:16:17

Sometimes  you have more customers than restaurants. Right.

1:16:22

Sometimes you have too many  restaurants, not enough customers. Yes.

1:16:24

So, it's very city dependent.

1:16:24

At Airbnb we  had basically many attempts at a dashboard of which market is supply constrained, which  is demand constrained.

1:16:29

Along the same lines, I think it's also something I think about with  B2B marketplaces, the reason they're challenging, in my experience, to work, there's so few of them,  is the supply is rarely fragmented.

1:16:38

Usually there are very few suppliers, so it's pretty easy.

1:16:43

"I'm just going to pick one of these 10 and I don't need you." Is that true?

1:16:47

Is that how you  think about the challenges of B2B marketplaces?

1:16:53

There's definitely that, but I think actually  the bigger challenge with B2B marketplaces is on the homogeneity of the supply.

1:16:58

When you think  about a lot of labor marketplaces, and let's take a classic example of Mechanical Turk, right?

1:17:05

What  you need in a marketplace for that flywheel...

1:17:05

I have a graph in my slides where you show that the  more you penetrate the market, the happier you're able to make your customer.

1:17:23

You should have an  exponential experience where the flywheel doesn't slow down.

1:17:30

Now you take Airbnb as an example,  there isn't a limit to how valuable it is to have more supply on Airbnb because everybody has their  own special preferences.

1:17:40

And there probably is a theoretical limit, but you just feel like there is  always going to be the, there's such heterogeneity in the supply for Airbnb, that that's what has  let Airbnb really close and escape competition.

1:18:04

With B2B marketplaces what sometimes happens,  like a labor marketplace, is that you have this homogeneity in the supply, where it's not  clear that adding the next incremental unit of supply actually changes the experience for  the demand side.

1:18:17

And so at Mechanical Turk, whether Mechanical Turk has a hundred thousand  Turkers or 5 million Turkers, it probably doesn't really change the experience for somebody who  is using Mechanical Turk.

1:18:30

And that's why in the early days, a Mechanical Turk, you saw a lot of  other copycats or clones of Mechanical Turk doing something similar because it didn't take that  much supply for them to be able to create an experience for a segment of the market that was  as good as the already scaled Mechanical Turk. Awesome.

1:18:55

I'm glad we got into that.

1:18:55

We're getting  real dirty about marketplaces.

1:18:55

Exactly what I was hoping for.

1:18:59

You said that you had something  else you wanted to share along these lines.

1:19:04

And there's so many other examples of reasons  why a marketplace won't tip competition.

1:19:04

Again, you're a food delivery company and you  go after the suburbs where there's no competition.

1:19:18

That makes your job really  easy to tip the market.

1:19:18

You go to New York City where you have an entrenched  competitor of Grubhub plus Seamless Web, a different culture around delivery where the  restaurants mostly have their own delivery fleets, and it's just going to be so much harder  for you to tip that market.

1:19:32

And so, I think you have to be really context aware  when you're building a marketplace of what your competition's going to be so that you see if there  is a path for you to actually tip the market.

1:19:52

And even if you've tipped the market, it may  get untipped, like Uber comes in and starts to eat your lunch, no pun intended.

1:19:55

It doesn't  last forever.

1:19:55

You have to keep fighting for it.

1:20:00

Well, and it's such an important point,  which is that you can never rest on your laurels when you're building a marketplace.

1:20:05

The history of places is one in which you have a marketplace that feels dominant and then  gets disrupted by a competitor.

1:20:12

HomeAway, VRBO being disrupted by  the likes of you at Airbnb.

1:20:23

I wish I could take credit for all that.

1:20:23

Yeah, so one way I think about it is you're  talking about this idea of tipping is, a simple way to think about if tipping is  happening, if you're tipping it successfully, is percentage of your growth that's starting  to come from organic word of mouth, people just becoming like, "This is the default way  I'm going to order food, travel, book a ride."

1:20:43

I think you see two things.

1:20:43

You see one,  the cohorts getting better.

1:20:43

So people start using you more.

1:20:50

As the supply side gets  more diverse, you have more and more use cases that you start to be able to serve.

1:20:59

And  so you get the demand side leaning in more, the cohorts get better.

1:21:05

And then to your  point, you have the organic growth that happens where you don't have to fight to  get each new participant on both sides of your market.

1:21:16

There's something that starts to  happen where the value proposition is just so strong relative to any other substitute  that the market starts coming to you. Awesome.

1:21:27

So essentially, cohort retention  starts going up because more and more valuable, and more people are coming to you, just word  of mouth or through some loops that you built. Exactly. Awesome.

1:21:37

Anything else on this layer/level  of the [inaudible 01:21:41] before? No. Okay, cool.

1:21:42

Let's talk about dominating  the marketplace and what that looks like, and how you do that.

1:21:45

How do you dominate  a marketplace and win, Sarah Tavel?

1:21:51

So yes, level three, and this is the one I feel  like every founder who starts a marketplace, they're chomping at the bit to be able to really  focus now on growth.

1:21:58

Because all along, I feel like we've been holding you back of just, "Focus,  focus, focus."

1:22:05

And what you're doing through level one and level two as you're honing what you're  building, is that you're basically building a playbook.

1:22:18

You don't yet know whether this playbook  is repeatable.

1:22:18

It's not always the case that the dynamics of one market is the same elsewhere.

1:22:28

I'll take REKKI as an example.

1:22:28

In the London food scene, there's significant fragmentation  of suppliers.

1:22:35

In the Berlin food scene, that's not the case.

1:22:43

And so it's not always the  case that whatever you did in one market works in another market, but usually there's something that  rhymes.

1:22:49

There's a hint of what is going to work.

1:22:56

So what happens now is you have a market  that's tipping, and the question then is, are you ready to take your eye off the ball  and start to diffuse your focus into other markets?

1:23:09

So there's kind of three vectors then  that any marketplace can grow at this point.

1:23:17

The first vector is within the existing  market where you already are tipping that market.

1:23:22

You as a founder then have  to make a very personal decision, that what you're looking at is the context  of your competitive situation.

1:23:29

So if you're tipping a market and you have no other  competitor going after that market, you're the first one to see this opportunity,  then I think you have two things that you want to do at the same time to grow.

1:23:46

The first thing is that you want to take the existing market that you're in  and you just keep doing what you're doing, and you may even find ways to stretch beyond  that initial market that you're going after- ...

1:24:02

Beyond that initial market that you're  going after, within the same market.

1:24:02

And so, what I mean by that is Uber went from black cars  to UberX to UberPool.

1:24:06

They kept on finding ways in the geographies where they were already dominant  to keep on getting stronger by expanding the use cases that they serve.

1:24:20

So you have continuing to  grow and penetrate the market, find ways to answer more use cases in that market that you can do,  especially if you don't have a lot of competition.

1:24:35

And then, the third vector of growth is you want  to then try to get as many plates spinning in as many markets that you can handle as quickly  as possible.

1:24:42

And this is like the blitz scale, right? This is the land grab.

1:24:48

And again, your  equity value that you're going to create is going to come from dominating the market.

1:24:56

And so you don't want to plant a thousand flags in a thousand markets at the same time,  spread yourself too thin, and not decidedly win any one market.

1:25:10

You always want to put more wood  behind fewer arrows.

1:25:10

The more scale that you have, the more cities or categories where you have the  flywheel starting to spin and you're starting to see the tipping point happen, the stronger  your company will be.

1:25:25

Each market that you get, you have scale in, where you'll have contribution  profit.

1:25:32

You take that contribution profit, you invest it in new markets.

1:25:38

The more  markets and contribution profit you have, the more venture capital you'll be able to raise,  which you then reinvest in growing.

1:25:43

And so, this is really the place where you are, as  aggressively as possible, while, at the same time, not losing sight of the fact that your goal is, in  each market individually, to dominate that market, you're trying to grow into as much possible  market opportunity as you possibly can.

1:26:09

And again, the reason this is so important  is most founders that are ambitious start with this.

1:26:14

They're just like, "Go big immediately, blitz scale.

1:26:17

We need to win fast before  anyone catches up."

1:26:17

And so, again, it's a reminder that's the final step,  once you've done these other two steps.

1:26:27

Yes, and it's such an important point,  because don't forget, you're always going to be vulnerable to competition.

1:26:32

And so, let's  say you have a million dollars, and you spread that million dollars of go-to-market costs  across 10 cities, spreading yourself really thin.

1:26:44

You have a competitor come in, and guess  what?

1:26:44

They put a million dollars into one city, they're going to win that city, and that's going  to set them up for greater success down the road, to keep on being able to get more capital and  more expense that they can put to work to grow those cities.

1:27:03

And of course, we never have one  competitor.

1:27:03

Always have a lot of competitors.

1:27:09

And so, focus on these steps is just, it really is  such an important thing to have discipline around.

1:27:17

And this is the reason that Uber  went big and raised so much money, invested so much to scale so fast, versus Lyft.

1:27:22

Same with DoorDash versus Uber.

1:27:22

Basically, they're both trying to dominate.

1:27:28

Neither one, I  guess, Uber, I don't know if it's safe to say, seems to have won in the market.

1:27:33

DoorDash versus  Uber Eats still very one and two-ish.

1:27:33

So I think a lot of people look at these companies, they're  like, "They raise so much money, they're losing so much money, they're never going to work."

1:27:43

But  they do this, because to build a durable business and to get the benefits of the idea of what the  marketplace they built, they need to dominate, they need to be number one by far.

1:27:52

And it  doesn't mean it always works.

1:27:52

DoorDash, even though they're bigger than Uber Eats,  from what I understand, they're not like...

1:28:00

I don't know, would you consider they're  dominant?

1:28:00

Or is it still a big challenge? I don't know. I don't know.

1:28:06

What  is clear is that they've built an incredible company.

1:28:11

It's just  an incredible...

1:28:11

They've done an incredible job of doing what they  do, and it is a crowded market still.

1:28:20

So you can still build a great business,  even if you don't dominate, dominate.

1:28:20

It's just you won't make as much money, nearly  as much profit, basically, your cash flow. That's right.

1:28:29

Something that you all at Benchmark are really  big on, which I think would be interesting to talk about, is the TAM not being as big a deal as  people think.

1:28:34

So a lot of times, there's a lot of marketplaces that start very small, and there's  a fear that the market is just not going to be big enough for them to build a massive business  long-term.

1:28:45

And you all don't worry about that as much as a lot of other investors, where the  market itself isn't a huge killer of investing.

1:28:57

I would underline it even, which is  that we get excited about the markets, the opportunities, that might  seem small from the outside. I love it.

1:29:05

Can you speak to that and help  people understand [inaudible 01:29:10]?

1:29:09

You remember the early days of Airbnb  like, "How big could this get?"

1:29:13

Yeah, I wasn't there that early.

1:29:14

Yeah, but you knew of it, and Etsy also  underestimated for years and years and years.

1:29:19

Hipcamp, that was part of what excited  us is that it was this market that was actually much bigger than people would have thought from  the outside.

1:29:26

And the wonderful thing about going after these underestimated markets is that they  don't have competition in the beginning.

1:29:33

And so, you have more of the elements of being  able to operate into a market and tip the market towards you, when you  don't have competition.

1:29:45

And so, we love these types of markets, and we  always say, to the founders out there, if other people are telling you the market's  too small, we would love to get to know you.

1:30:00

I think a lot of founders will love hearing  this.

1:30:00

I think it's also important to add something you've shared with me is it's important  for there to be adjacent markets that are big, for you to have the potential to  expand it to [inaudible 01:30:11]. Right.

1:30:10

And yeah, it's such an important point.

1:30:10

The market itself, it can't be a cul-de-sac.

1:30:10

You need to start somewhere that has the potential to  grow beyond that, but in the beginning, it's going to look small.

1:30:24

Let me give you the example of  Hipcamp.

1:30:24

Hipcamp, when we invested, was literally land.

1:30:30

It was land where people...

1:30:30

I don't know,  Lenny, if you're a camper. I unfortunately am...

1:30:38

Yeah, I love Hipcamp by the way. Okay, well, amazing.

1:30:39

Well, if you have a tent and  a sleeping bag and you're not afraid to put your thermos in a running river and clean the water,  then that was the early days of Hipcamp.

1:30:46

It was for the hardcore camper, which itself, feels like  a very small market.

1:30:53

It's not actually that small, but it is a smaller market than other people  might themselves get comfortable with.

1:31:01

But then, what would happen is that hosts on Hipcamp, and  I stayed at one of these Hipcamps, and it's just such an incredible experience, the host started  to make a little bit of money from Hipcamp.

1:31:13

And they took that money, and they started to invest  in structures on their land.

1:31:21

So in the beginning, maybe it was a fire pit or a bathroom or shower,  and then, it became a tree house or a yurt.

1:31:34

And so, what happened with Hipcamp is that, in the  beginning, it was going after this very different market segment, but as they became successful,  made their landowners money, those landowners invested that money back into their land and  started to open up the market opportunity for Hipcamp, into people more like me, that are  glampers, that want that experience in nature, but maybe don't want to pitch a tent to have it.

1:32:01

And so, that's kind of one of those examples of an underestimated market that ends up growing beyond  that.

1:32:06

There's warning stories here too. I always think of Etsy.

1:32:14

So Etsy, I remember, actually, when  I was at Pinterest, being driven crazy by Etsy, because Etsy was all about handmade goods.

1:32:22

But as they were running up to going public, they started to chase GMV.

1:32:29

And what  that looked like is that they started to have a lot of mass produced goods on Etsy.

1:32:34

It drove me crazy at Pinterest, because there was this one seller of these scarves, that was  clearly a mass produced scarves, and they were spamming Pinterest constantly with pins of those  scarves.

1:32:48

And it was just very clear that Etsy had kind of lost its way in that moment.

1:32:56

They would  start to chase GMV growth.

1:32:56

They were going beyond what they actually stood for, and they ended up  having a real reaction from the sellers that were making handmade goods and the buyers.

1:33:09

It was  this big erosion of trust, and they ended up, I don't know if it was related, but it ended  up precipitating, I think, a CEO change, to the CEO that is there now and who has obviously  done an incredible job building Etsy from there.

1:33:26

Yeah, we had the VP of product from Etsy on  the podcast.

1:33:26

And we talked about that actually, what that transition was like, because it was  pretty dramatic.

1:33:29

They went from very warm, fuzzy, cozy vibes to, "We need to build a business that  lasts.

1:33:34

Let's change the way we operate."

1:33:34

While we're on this topic of what gets you excited about  marketplaces, this is something Mike suggested I ask you, so I love that you get excited when  it's a small market, very contrarian, what else, when founders are pitching you, let's say with a  marketplace, what else do you look for?

1:33:50

Whatever you can share off the top of your head that you  look for that gets you excited about marketplace. It's a couple things.

1:33:59

One is, and I'm thinking  actually of one founder I met recently, where there's that earned secret, where they  see a market opportunity that other people are overlooking, that hasn't been addressed.

1:34:11

Maybe  there's a reason why it hasn't been addressed in the past, but now is the moment, there's  something changing that's creating a current in the market.

1:34:23

We could talk about currents later,  if we want to, but that there's something that's creating momentum in the market, that's opening  up an opportunity for this marketplace to exist.

1:34:34

And for whatever reason, that founder is the  person who sees it.

1:34:34

And it's kind of one of those things that, once you see it, you're like,  "How does it still work this way?"

1:34:40

And it makes so much sense for somebody to come in and do  something about it.

1:34:45

And then, the second thing that always just deeply resonates, and it's  obvious at this point why this would be true, is a founder then that really has focus.

1:34:57

And it's kind of back to focusing their ambition, like a laser beam, as opposed to this broad sun  trying to do everything.

1:35:05

And so, you really feel like they're focused on the right things,  and that actually leads to the third thing, which is you really feel, when a founder is either  trying to fool you or fool themselves with vanity metrics, versus the true intellectual  honesty and the intellectual rigor of, "What's really working in my business? What's not  working?

1:35:32

Where are we focused to make that the best it can be?"

1:35:38

And man, that is always, that's  how you build long-term, enduring value, and it's something that I think it's consistent across  all the founders I'm lucky enough to work with.

1:35:52

What I love about this answer is something  I often say about marketplaces is that most of your problems are not marketplace  problems or questions.

1:35:57

It's just what every startup has to deal with.

1:36:01

So what  you shared is basically an earned secret, which will apply to any business, which maybe  emerges a current in a wave that you can ride, having great focus and also focusing on the right  metrics. I 100% agree.

1:36:11

And it's also interesting, it could be a marketplace, it cannot be,  and I think people often overweight how much...

1:36:22

"I'm building a marketplace and  I need to think of everything," from this marketplace perspective versus 95% of your  challenges, questions, hurdles are going to be just whatever startup has to deal with.

1:36:32

And  then, there's a bit of specific to marketplace.

1:36:36

And I want to just double click on the current  thing, because it's very related, which is a lot of people, and this is back to maybe our  contrarian take on markets, I think a lot of people think about markets almost like these  bodies of water.

1:36:46

And it's like, "Oh, it's this big body of water that we're going after."

1:36:52

And I  actually think that the most interesting markets, you have to think of them like currents, where  there's something happening in the market that's creating this current, where you can have a  plank of wood that you've put on the river and it's going to pull you forward, versus a market  that doesn't really have that momentum to it, you're going to have to build something really big  and fancy to make any progress.

1:37:18

And that's why we care less about market size, because really,  what you're looking for when you're looking at a market are what are the dynamics of change,  what's the current and momentum that's going to pull the company and make the job easier for the  founders to actually build something that endures? Essentially, "Why now?"

1:37:40

is how a lot  of people think about this, right? Yes, yes.

1:37:44

I love just the visual of a current.

1:37:44

There's a startup I invested in, as an example of the opposite, that's a crypto  marketplace sort of thing.

1:37:48

And they started it when crypto was really great, and they  continued building it as crypto winter emerged.

1:37:58

And they just realized, "Our timing,  this is not the time to build a crypto company, that's new, that's trying to compete with  who's out there."

1:38:04

And so, it's an example of the...

1:38:08

You got to recognize when the wave  is going the opposite direction and everything is pulling you away from success.

1:38:13

The  opposite of what you're describing. Yes.

1:38:16

I might have a nuance there, because  I think crypto is too broad of a way to describe it.

1:38:24

If you said it was a DeFi crypto  company, then yes, definitely, with treasuries where they are, the opportunity in DeFi isn't  as material as it once was, which stablecoins, I'm a huge believer in stablecoins, and  I think that's a market where we have a real current.

1:38:44

With inflation and so many local  currencies, there's real demand for stablecoins, the US dollar stablecoin, that comes in many  different shapes and forms, that is something that I believe has a very strong current right  now, that I'm actually quite excited about. Oh, interesting.

1:39:01

Yeah, I should have been  clear.

1:39:01

It's like a very specific part of crypto that's just not happening  too much, versus what it was.

1:39:04

Okay, we've gone totally off track.

1:39:10

So let me  come back to our track and see what else you wanted to share around the hierarchy  of marketplaces either on the top... That's it. Okay. We did it. Amazing. Yes.

1:39:20

I have a couple more questions  sort of related, but I guess, is there anything else that you wanted to  say about the hierarchy of marketplaces?

1:39:27

Maybe just this kind of the coda, which is  like you can never rest on your laurels, and we talked about this already, but the history  of marketplaces is one of disruption.

1:39:32

And the idea with happiness is that, and Amazon and  Bezos talk about this, which is expectations, consumer expectations, are constantly going up.

1:39:48

And so, if you ever stagnate in the experience that you give to the consumer, guess what?

1:39:55

You're going to get disrupted.

1:39:55

And the examples of we talked about with Airbnb and HomeAway,  DoorDash, and Grubhub, Grubhub wasn't able to, for different reasons, they were a public company,  and so, they couldn't access capital in the same way that the private markets could.

1:40:14

But they  were too slow to change the atomic unit of their supply to have delivery that they fulfilled.

1:40:21

And so, they got disrupted by the DoorDash, Uber Eats of the world.

1:40:27

And so, you just  can't rest on your laurels.

1:40:27

Expectations constantly go up.

1:40:34

And it's part of what's so  exciting about this market that we play in.

1:40:40

I think Grubhub is a great example of that,  where they were the first really successful food delivery company, and then, even with network  effects, by far, the best way to order.

1:40:43

And then, DoorDash comes around and wins, because  they go bigger and spend a lot of money that Grubhub wasn't willing to spend. Awesome.

1:40:54

So I guess the advice there is just don't take for granted your success,  even if you have amazing network effects. That's right. Okay.

1:41:03

So as we were chatting  about this conversation, something you mentioned is that, even  if you're not building a marketplace, these lessons are actually still useful.

1:41:10

So  say you're building an open source product or a social network or even a SaaS startup, a  lot of these sort of lessons can still apply.

1:41:20

What advice would you have for people  that have heard what you just shared, but aren't necessarily building a marketplace?

1:41:23

What are some of the takeaways as well?

1:41:26

At Benchmark, I'm lucky that I have partners  who look at very different types of companies that I look at, and we meet such a incredible  breadth of founders.

1:41:32

And what you just realize, again and again, is that these same  lessons hold.

1:41:38

With open source, it's about solving a specific developer's need in  the beginning and solving it really freaking well, and then, expanding from there.

1:41:49

With SaaS,  I think maybe the fascinating exception, kind of similar to your Thumbtack exception, I  think what Parker Conrad's doing with Rippling and this idea of a compound startup  is very different.

1:42:01

And actually, he has a level of ambition that is both the  sun and a laser at the same time.

1:42:06

And so, that's kind of, in a rare founder, you can have  that level of execution, but again and again, what you see, and I think a lot of this,  for new companies leveraging large language models to build products, is that focus on a  constrained market to start is the way to win. I like that.

1:42:34

Basically, it's happy developer in  the case of DevTools or happy enterprise user, just get happy people using your product and  coming back to it.

1:42:40

So I love that as a reminder.

1:42:46

One other question is you wrote this post on  finding white space in building marketplace, basically someone that wants to build  a marketplace, trying to figure out, where is there an opportunity for new marketplace?

1:42:54

Do you have any advice for people, say, founders, potential founders, that are looking  for ideas and opportunities to build a marketplace for how to find one?

1:43:02

Where do you think there's opportunity?

1:43:05

It's kind of fun to ask the question whether LLMs  change the game or open up new surface area.

1:43:05

So in my post, I write about three ways that you can  look for a new opportunity.

1:43:15

I think it was like, number one, you always find a horizontal  marketplace and you find the kind of low NPS part of that segment and you create a marketplace  around that.

1:43:26

eBay, being a horizontal marketplace, the sneakers being a low NPS part of that, and  you get GOAT.

1:43:34

The second is finding a niche that no one else is paying attention to.

1:43:42

And the  Etsy examples we gave, the Hipcamp stories, and bringing that online, taking friction away,  and showing that it's actually a bigger market than you think.

1:43:55

And then, the third is changing  the atomic unit of the supply.

1:43:55

So that kind of like Grubhub, the atomic unit there was a  restaurant that has its own delivery fleet, and then, Postmates, DoorDash, Uber Eats  came in and said, "Actually, it's any restaurant, we'll provide the delivery fleet."

1:44:13

And so, they opened up the available supply.

1:44:13

Now, when I think about LLMs, I think there's a real  opportunity for the third one.

1:44:19

LLMs may make it possible to bring on a supply type that maybe the  long tail, that was just, it was too much effort to reach out to them, onboard them, but maybe if  you automate that work, you actually create an opportunity to expand the supply in a way that  none of us can anticipate right now.

1:44:41

And then, who knows whether there's an opportunity  with LLMs to create a better experience in one of these kind of low NPS segments of a  market or a niche market itself, that makes it possible to bring it online.

1:45:00

So I haven't seen  anything yet, but I am definitely on the hunt. Very cool.

1:45:05

Turned into AI corner,  which I love.

1:45:05

Okay, well, with that, we reached our very exciting  lightning round. Are you ready? Okay, I'm ready.

1:45:16

What are two or three books that you've  recommended most to other people?

1:45:22

Pachinko is one of the best fictional books  I've read in a while.

1:45:22

I just loved it, and so, I highly recommend that.

1:45:26

And then, to founders,  I am a sucker for The Five Temptations of a CEO and The Five Dysfunctions of a Team.

1:45:34

It's kind  of like you imagine those books in the grocery store aisle, but they're fast reads that are  incredibly insightful and I highly recommend.

1:45:46

Is there a favorite recent movie  or TV show that you really enjoy?

1:45:51

I don't watch stuff, so I'm  not a good candidate there. I highly respect that.

1:45:55

Is there  a favorite interview question that you like to ask candidates,  which usually, we can transform into when you're talking to founders and  trying to decide if you want to invest?

1:46:06

I always love hearing the journey people take and  specifically how they've made decisions along the way, what drives them from each step.

1:46:13

I  think that's always very illuminating.

1:46:19

Do you have a favorite product you've  recently discovered that you really love, whether it's an app or physical product that  you've used often?

1:46:23

Anything real cool or fun?

1:46:31

I'll say we are late joiners to Tesla, my family.

1:46:31

And man, it is one of those products that you use it for the first time, and you're just  like, "I could see why I'd want to own equity in this company," not financial advice  obviously, but it's just an awesome experience. I completely agree.

1:46:53

I've gotten so used  to, we have a regular car and a Tesla, and the fact that you don't need a key anymore,  you just walk up and open it, because it has your phone...

1:47:01

My wife, she left the key in our  Subaru, just because she's like, "Oh, shit, I need to take the key out."

1:47:08

It's just sitting  there running.

1:47:08

Yeah, you're so used to just the casual just walk up, open, you're good to go. Awesome.

1:47:13

Do you have a favorite life motto that you often repeat to yourself, share with people,  either in work or life, that you find useful?

1:47:25

My partner at Greylock, Reid Hoffman, has this  line of every strength has a corresponding weakness, and vice versa, and there's so much  wisdom there.

1:47:31

We see our own strengths and we see our weaknesses, but not realize that they  actually go together.

1:47:40

You can't have one without the other.

1:47:46

Similarly, strengths in organizations,  like a decentralized organization can move really quickly, and the corresponding weakness of that  is that it can feel chaotic and disorganized.

1:47:54

On the other side, a centralized organization can  feel really slow, but it is very intentional in the decision-making and the control of the  experience.

1:48:07

And so, everything has trade-offs, and realizing that, more often than not, they come  together, it's just so useful to be aware of that. Awesome. Final question.

1:48:20

I believe you  played rugby at some point, is that right? Yes. Okay.

1:48:25

Is there a rugby story that would be fun to  share from your time playing rugby?

1:48:25

And if not, what should people know?

1:48:30

What would surprise  people about rugby, that they may not be aware of?

1:48:36

Well, what people might be surprised  of, especially if they meet me, is that I was actually a really good tackler,  and I think I broke my nose a couple times and have more injuries than I would care to remember,  but I definitely inflicted more injuries on other people than I received.

And I think rugby is,  there's a camaraderie that comes with rugby, and the one thing I'll confess is that  we always joke that the rugby team is, it's not a rugby team, it's a drinking  team, that has a rugby problem. Amazing.

1:49:18

Those times are behind me. Oh, man.

1:49:20

It sounds like an awesome person to have in your court when you're a  founder, the best tackler in town. Heck yes. Amazing.

1:49:27

Sarah, I'm not surprised this went  as long as it did.

1:49:27

Thank you so much for being here. Two final questions.

1:49:32

Where can  folks find you online if they want to reach out and maybe ask follow-up questions?

1:49:36

And how can listeners be useful to you? I appreciate that. I'm Sarah at Benchmark.

I'm  on Twitter, Sarah Tavel, and I have a Substack, SarahTavel. com.

1:49:50

If you're a founder,  you're working on something, don't be shy.

1:49:52

We're in the business  of meeting with people like you, and so, I always love to get  stimulated by new ideas and people.

1:50:03

Just to focus people even more  there, is there stage you like, is there markets, anything people  should know of what's right for you?

1:50:09

We, at Benchmark, we're early stage.

1:50:09

We're an  early stage firm.

We aspire to be first board member.
