Key Takeaways

  • Venture capital functions strictly as an asymmetric return engine, not a capital preservation vehicle like treasuries, real estate, or private equity buyouts.
  • Over-diversifying a venture portfolio across hundreds of positions eliminates dispersion and strips out convexity, leaving an allocator with public market beta at private market illiquidity.
  • Poor LP alignment creates LP capture, forcing fund managers to liquidate generational assets like Anthropic at a 5x return or SpaceX at a 3x return to satisfy short-term cash calls.
  • Gavin Ezekowitz and Matt Collo manage cycle volatility through Ezekowitz and Collo's Pacing and Sizing Allocation Framework.

The Ezekowitz and Collo Pacing and Sizing Allocation Framework

Allocators frequently fail in venture capital because they treat fund commitments as isolated bets rather than continuous balance sheet operations. Ezekowitz and his partner Matt Collo structured this framework to maintain solvency across multi-decade market cycles:

  • Principle 1: Program Pacing

Develop a program, multiple funds, multiple years.

  • Principle 2: Program-Level Sizing

Ensure that the size is adequate that you can continue that program over time.

  • Principle 3: Position-Level Sizing

Size them on a matrix that allows you to take sufficiently sized bets over time such that no one bet wipes you out. As I say, the dead don't compound. You got to survive.

When This Works (and When It Doesn't)

This framework fits individual investors, family offices, and emerging allocators who must survive unpredictable macro corrections without abandoning their deployment schedules. It prevents the common allocator error of overcommitting capital at market peaks and retreating during downturns, which guarantees missing the generation-defining vintage years.

Where the framework fails is in institutional mega-funds managing tens of billions in assets under management. Mega-funds cannot maintain strict position-level sizing without writing checks so large they distort company valuations and dilute target ownership stakes. If an allocator runs a multi-billion-dollar pool, disciplined pacing often breaks down because institutional mandates force managers to deploy capital on artificial two-year fund cycles regardless of opportunity quality. In those structures, capital preservation mandates choke off the very asymmetry the asset class exists to capture.

Why It Matters

Venture returns are not normally distributed. They follow a strict power law where a tiny fraction of companies produces virtually all industry gains. As David Weisburd points out, venture capital has one singular role: to deliver asymmetric returns once in a while. When institutional allocators treat venture like an index fund by spraying capital across hundreds of seed-stage bets, they trade off power-law outcomes for false safety. As Ezekowitz explains: “What you lose in that which is the problem is because of the dispersion you you end up losing all the convexity and the only reason to do venture is convexity.”

At the same time, fund mechanics often sabotage compounding. The pressure known as LP capture occurs when allocators panic during market downturns, freeze capital calls, or push general partners to return cash. When an LP demands early liquidity, a fund manager is frequently forced to exit positions in outlier winners like SpaceX or OpenAI years before the actual inflection point. The winners get sold to cover the losers, flipping the venture model on its head.

Surviving twenty years in private tech markets requires recognizing that flat return periods happen even to top-tier investors. The investors who build real wealth in private tech markets do so by pairing high-conviction ownership in generational winners with strict balance-sheet pacing that withstands liquidity panics.
