The Biggest Mistake Investors Make When Building a Venture Portfolio

Описание: 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.

Highlights:
Why longevity in venture investing creates perspective most LPs never develop
The hidden edge elite LPs have in portfolio sizing, not just manager selection
Why governance may be the most underestimated driver of venture outcomes
How to structure a venture allocation after a liquidity event
The real reason venture portfolios feel “spiky” and why that is a feature, not a flaw
Why waiting for obvious top managers often leads to second-tier access
How fund cadence compression can quietly distort portfolio construction
The importance of underwriting firms, not just individual funds
Why benchmarking venture is especially challenging in Mag-7 dominated markets
Growth equity as the “third bowl of porridge” between venture and buyout
Co-invest adverse selection risks and how scale improves access
Systematic vs opportunistic co-invest strategies and when each makes sense
