Key Takeaways

  • Adams Street Partners analyzed 40 years of proprietary records covering tens of thousands of portfolio investments, concluding that 7% of companies generate all returns while 93% wash out.
  • The venture firm universe grew eightfold from 500 to more than 4,000 managers, increasing competition for access to top-quartile assets.
  • Traditional early-stage specialists like Union Square Ventures and Benchmark raised dedicated growth funds to protect their ownership in breakout assets.
  • Outlier outcomes now reach trillion-dollar market caps in public markets, compared to just five or six years ago when Apple stood alone above that threshold.
  • Late-stage growth checks can still generate venture-scale multiples because private companies capture value that previously accrued on public exchanges.

The Math Behind the Seven Percent Rule

For four decades, Adams Street Partners tracked investments across tens of thousands of venture-backed businesses. The distribution of returns never smoothed into a bell curve.

“Our data tells us that 7% of venture-backed companies generate all the gains and the rest 93% is just a wash,” (play from 45:27) Jeevarathnam explains. "It's just noise."

That distribution dictates LP portfolio construction. In a market where 93 out of every 100 bets return nothing net of capital, fund selection cannot rely on broad indexing. As Jeevarathnam notes: “Our job with the direct venture investments we're making into companies is to double down our exposure as much as possible to what'll end up potentially in that 7%.” (play from 53:21)

When the venture fund population sat at 500 firms, LPs could achieve index exposure to top deals simply by backing established brand names. With more than 4,000 venture shops marketing funds today, capital dispersion creates a dilution problem. Capital flows to average managers who capture the 93% wash, dragging net returns down to public equity medians.

Why Growth Equity Still Follows Power Laws

Venture economics historically assumed power laws applied strictly to seed and Series A checks. Once a company crossed $100 million in ARR, financial buyers expected returns to normalize around 2x to 3x cash-on-cash multiples.

That assumption broke as value creation migrated into private hands. Weisburd points out that elite early-stage franchises are adapting: “I talked to USV, Benchmark, they're raising their growth funds for the first time. They believe that power law still exists at the growth stage.” (play from 1:13)

The skepticism makes sense on paper. Writing a $100 million check at a $2 billion valuation leaves very little margin for error if an IPO tops out at $6 billion. But Jeevarathnam points to how the absolute ceiling on market cap has shifted:

“What's stunning to me is that we're even talking about a trillion dollar plus valuation for an IPO because it's easy to forget that until what, 5, 6 years ago, there were no companies in the world... Apple became the first one to cross a trillion dollars in value, and even today there are maybe 10 companies, 11 companies in the world with a trillion plus in market cap.” (play from 54:43)

When total addressable markets can sustain multiple trillion-dollar valuations, a company entering the growth stage can still expand by 20x or 50x. Jeevarathnam concludes: “If venture can find outliers at that scale of addressable market and therefore value creation, the power law will still apply and be true in the growth stage as well.” (play from 55:25)

The Squeeze on Pure-Play Late Stage

This shift forces a tactical recalibration for growth equity. When firms like Benchmark and Union Square Ventures raise late-stage vehicles, they disrupt traditional growth syndicates. Early-stage sponsors own information rights, board seats, and founder trust from the start. They can preempt Series C and Series D rounds before an external growth fund ever sees the pitch deck.

Meanwhile, companies stay private longer to absorb the steep part of their growth curves. Early-stage funds running growth vehicles capture the entire lifecycle of the 7% winners. Late-stage shops without proprietary early-stage pipelines find themselves priced into the 93% wash, underwriting crowded auctions at peak multiples.

Why It Matters

Mega-cap exits are redefining private market economics by extending power-law distributions into growth equity. As total market ceilings expand into the trillions, early-stage firms with dedicated growth pools can capture outlier gains that once belonged to public investors. Growth managers who lack early pipeline access face severe adverse selection, competing for assets that fall outside the winning 7%.
