Power-law returns

Venture returns do not look like a bell curve. They look like a power law: most investments return little or nothing, a thin middle returns a few times the money, and a tiny tail returns so much that it pays for everything else. Once you see that shape, partner behavior stops looking greedy or random.

The big idea

Industry studies of large deal sets keep finding the same pattern. Correlation Ventures' widely cited analysis of tens of thousands of financings found that a large majority of deals return less than the capital invested, a small slice returns more than 10×, and a fraction of a percent returns more than 50× — and those extreme outcomes dominate aggregate returns across the asset class. Horsley Bridge's long look at its own portfolio famously attributed a large share of total returns to a small percentage of deals (on the order of single-digit percent of deals driving most of the dollars). Exact percentages shift by vintage and dataset; the shape does not.

At the fund level, Carta and other trackers describe the same story in operational language: in a typical fund with a few dozen companies, one to three investments often produce the majority of the fund's returns.

Paul Graham called the strategy black swan farming — deliberately hunting for outlier outcomes rather than maximizing the hit rate of "pretty good" companies. The arithmetic of a fund returner is why that farming is rational.

Walking through a twenty-name sleeve

Twenty investments of $2M each = $40M deployed. Nineteen go to zero. One returns 50× on its $2M → $100M proceeds. That single name returned 2.5× on the $40M sleeve before fees on the rest of the fund. Ugly hit rate; acceptable arithmetic if ownership held.

Now change the winner to 5× on $2M → $10M proceeds. Hit rate identical; fund math collapsed. The shape of the winner matters more than the count of losers.

Common mistakes

• Judging a fund by hit rate. Nineteen zeros plus one 50× can beat ten 3× outcomes.
• Treating a 2× or 3× as "the plan." Those help; they rarely clear the LP bar alone.
• Quoting one study's exact percentages as laws. Vintages move; the heavy tail does not.

Check yourself

In a typical fund of a few dozen companies, how many names often produce most of the returns?

One to three.

Nineteen of twenty deals go to zero, one returns 50× on a $2M check. What are the proceeds from that winner?

$100M — 50 × $2M.

Key takeaways

• Venture returns follow a power law: a few deals produce most of the dollars.
• One to three names often make the fund.
• The winner's shape (50× vs 5×) matters more than how many others died.
• Exact percentages vary by vintage; the tail does not.
