EP273: What the Best Family Offices Do Differently

What if managing your own capital and not outsourcing it is the highest-return investment decision you can make? In this episode, I talk with Alex Tonelli, Co-Founder of Endurance, about what changes when entrepreneurs manage their own money with the same first-principles thinking they use to build companies. Alex explains how Endurance evolved from a startup holding company into a highly structured family investment office, why principal-driven capital behaves differently than institutional capital, and how disciplined portfolio construction, vintage diversification, and contrarian thinking create durable long-term returns. We also explore why institutions systematically underperform their opportunity set — and how to avoid the behavioral traps that cause it.
