Fund Structure
Last updated
Quick Answer
The degree to which a fund's value is concentrated in a small number of portfolio companies, which increases both upside potential and downside risk.
Portfolio concentration measures how much of a fund's total value is attributable to its top holdings. High concentration — where 1-3 companies represent 50%+ of fund value — amplifies both returns and risk. In venture capital, concentration naturally increases over time as power law dynamics cause a small number of winners to dominate fund value while the majority of investments fail or underperform.
In Practice
By Year 5, the fund's portfolio concentration had become extreme: one breakout company represented 65% of total fund value, the second-best company was 15%, and the remaining 28 companies combined for just 20%. The fund's return was almost entirely dependent on the outcome of a single company.
Why It Matters
Portfolio concentration is a feature, not a bug, of successful VC funds. The power law means the best funds are often the most concentrated. However, managing concentration risk — including timing of exits and follow-on decisions — is critical to converting paper gains into realized returns.
VC Beast Take
There's a tension between diversification (which reduces risk) and concentration (which drives returns). The data shows that top-performing VC funds tend to be more concentrated than median funds. But correlation isn't causation — concentration in winners looks brilliant; concentration in losers is catastrophic.
