Limited Partners should resist pressuring VCs for early exits to lock in DPI. The best companies compound value at incredible rates, making it optimal to hold winners. Instead, LPs should manage portfolio duration and liquidity by building a balanced portfolio of early-stage, growth, and secondary fund investments.

A fund showing a 7x return on paper is already a massive success. The logical move is to sell positions and realize those gains for LPs. The tendency to "go for it" reveals a flawed incentive structure that prioritizes future potential over locking in exceptional returns.

Even with big wins, a venture portfolio can fail if not constructed properly. The relative size of your investments is often more critical than picking individual winners, as correctly sized successful investments must be large enough to overcome the inevitable losers in the portfolio.

To meet its 60% budget support obligation without holding excess cash, the Williams endowment obsesses over liquidity. Weekly cash flow reviews and credit lines allow them to keep only 1-2% in cash, ensuring the vast majority of the portfolio is always in the market and compounding.

Investors fixate on selecting the right companies, but the real money is made or lost in the decision of when to sell or hold a winning position. The timing of an exit can create a 100x difference in outcomes. Having a disciplined approach to portfolio management and liquidity is more critical to fund performance than the initial investment choice.
