In this episode, Patrick interviews Henry Ellenbogen, founder of Durable Capital Partners. Henry shares his investment philosophy of finding the 1% of companies that become long-term compounders, growing 6x over 10 years. He discusses "Act Two" entrepreneurs who leverage previous experience to build better companies, the importance of studying business history, and how AI represents a transformative shift comparable to the internet. Henry explains Durable's unique approach of investing in companies from private stages through public markets, their focus on people and change, and why going public can benefit growing companies. The conversation covers market structure changes, competitive advantages, team building, and Henry's belief in balancing growth, profitability, and innovation for sustainable success.
