What does it take to manage the wealth of America’s most iconic families? In this episode, I spoke with Stephan Roche, Partner at BanyanGlobal, and former senior executive for the Gates and Walton families. Stephan has had a front-row seat to how some of the world’s most sophisticated family offices think about investing, governance, and multigenerational legacy. At Banyan, he now advises enterprising families on ownership strategy and purpose. We explore the frameworks ultra-wealthy families use to structure portfolios, co-invest alongside GPs, and prepare future generations for stewardship—not just of capital, but of mission and values. Whether you’re managing family wealth or building toward it, this is one of the most insightful conversations I’ve had on long-term investing.
