Quick Answer
The systematic distortion in VC performance benchmarks caused by survivorship bias, selection bias, and reporting delays.
Benchmark bias refers to the various systematic distortions that make venture capital performance benchmarks unreliable compared to public market benchmarks. Key biases include survivorship bias (failed funds stop reporting, inflating averages), selection bias (better-performing funds are more likely to report), reporting lag (valuations are updated infrequently), and methodology differences between benchmark providers. These biases can overstate the asset class's true performance by 200-500 basis points.
In Practice
The GP cited Cambridge Associates data showing their fund in the top quartile, but the LP's due diligence revealed that the benchmark suffered from significant survivorship bias: roughly 30% of funds in the comparison set had stopped reporting, likely because their performance had deteriorated.
Why It Matters
Benchmark bias can mislead LPs into thinking VC performance is better than it actually is, or that a specific GP is outperforming when they're actually performing in line with (or below) accurately measured benchmarks.
VC Beast Take
The VC industry has a benchmarking problem that no one has fully solved. Unlike public markets where performance is measured daily with complete data, VC benchmarks are constructed from incomplete, self-reported, and delayed data. Sophisticated LPs adjust for these biases; most don't.
