E323: How Billionaires Build Their Portfolios

What does it take to build a world-class private equity portfolio for an 800-year-old institution? In this episode, I sit down with Sam Sturge, Head of Private Equity at the University of Cambridge endowment, to discuss how he rebuilt the program with a mandate to generate inflation plus 5% returns for generations. Before joining Cambridge, Sam worked at Morgan Stanley and Partners Capital, and today he oversees a concentrated portfolio of buyout and venture relationships within the university’s £4.5 billion endowment.

What changes when wealth stops being about building and starts being about preserving? In this episode, I sit down with Jonathan Dane, CIO and Founder of Defiant Capital, to explore how family offices think about portfolio construction after a major liquidity event. Drawing on his experience at Goldman Sachs and Jefferies, Jonathan explains why independent advice matters and how families navigate the transition from wealth creation to long-term preservation.

What if one of the most overlooked $700 billion pools of capital in the U.S. is quietly shaping private markets? In this episode, I sit down with Jennifer Mink, President of Investment Performance Services, an investment consulting firm overseeing roughly $70 billion in assets under advisement, to discuss how Taft-Hartley pension plans approach long-term investing. Jennifer shares how IPS designs portfolios that balance public and private markets, using disciplined asset allocation and diversification to improve overall portfolio efficiency and manage risk across market cycles.

Why are private markets still managed in spreadsheets when hundreds of billions of dollars are at stake? In this episode, I sit down with Ryan Eisenman, Co-Founder and CEO of Arch, a platform supporting more than 550 clients and over $405 billion in alternative assets. Arch is building an operating system for private markets that helps investors manage the operational complexity of alternatives across private equity, venture, hedge funds, credit, and more, bringing modern infrastructure to a part of the financial system that has historically relied on manual processes and fragmented data.

What if the best private equity opportunities are the ones no one else is set up to pursue? In this episode, I sit down with Jeff Collins, Founder and Managing Partner of Cloverlay, to explore how he built a $2 billion firm by going where capital isn’t. After 14 years at Morgan Stanley Investment Management, Jeff spun out to focus on what he calls “uncorrelated private assets” - niche, often overlooked segments where return dispersion is wide and operator selection matters more than financial engineering.

Why would an LP invest in the GP instead of the fund… and what problem is GP stakes really solving? In this episode, I sit down with Todd Owens, Managing Partner of Cantilever Group, to unpack the world of GP stakes. Todd explains what investors are actually buying when they take a minority stake in an alternative asset manager, why liquidity risk is the central challenge, and how structural innovation could reshape the asset class.

What separates elite venture LPs from everyone else… and why do most family offices underestimate the governance required to win? In this episode, I sit down with Michael P. Larsen, a longtime Partner at Cambridge Associates, to unpack nearly two decades of building venture and private equity portfolios for leading institutions and family offices. Michael shares why longevity may be the ultimate competitive advantage in asset management, how governance quietly determines venture outcomes, and why portfolio size can matter just as much as manager selection. We dive into power laws, spiky returns, growth equity’s overlooked role, co-invest best practices, and how benchmarking can help LPs stay disciplined during optically challenging cycles.

What if the biggest untapped source of alpha isn’t better investments… but better tax structure? In this episode, I sit down with Andrew Berman, Co-Founder and Managing Partner of Arcitell, to explore the overlooked power of tax-aware private real estate investing. After starting his career at AQR Capital Management and working closely with one of its co-founders inside a family office, Andrew saw firsthand how tax-aware strategies transformed public market investing. He realized private markets had yet to fully adopt the same discipline. We break down structural alpha, why many private real estate managers are incentivized to sell too soon, and how taxable investors can materially improve long-term wealth creation by aligning investment strategy with tax structure. In increasingly efficient markets, tax may be one of the few durable advantages left.

What if the easiest alpha in public markets isn’t stock picking… but taxes? In this episode, I sit down with Zach Wainwright, Founder of Twin Oak ETF Company, to break down structural alpha, ETF tax efficiency, and how high-net-worth investors can compound capital more intelligently. Zach shares lessons from his time at Wellington, TIFF, and inside a single-family office — and why long time horizons, incentive alignment, and tax awareness may be more powerful than traditional stock-picking alpha. We also dive into tail-risk hedging inside an ETF wrapper and how families can design portfolios to survive extreme drawdowns without sacrificing long-term compounding.

What if success isn’t about talent… but about multiplying your effort by 10? In this episode, I sit down with Grant Cardone, CEO of Cardone Capital, to break down the mindset behind the 10X Rule, omnipresence in marketing, raising billions from retail investors, and why quantity always precedes quality. Grant shares how he built a $5B real estate portfolio, scaled a media machine that sends hundreds of millions of emails per year, and combined Bitcoin with multifamily real estate to create a new hybrid investment vehicle. We also unpack why most people underestimate effort, why repetition builds self-esteem, and why illiquidity may be the real edge in investing.
