Reconstructed first-round book from the research data, not a scrape of today's website. Public portfolio pages over-report winners, and this graph has the same public-data bias. Investor edges are essentially Crunchbase through late 2015, plus Y Combinator.

Ranked when at least 15 labeled deals have a vintage base rate. Rank is the average-rank percentile of shrunk excess (20 pseudo-deals at that book's vintage base rate) among eligible VC books that clear the same minimum. 100 is best. The whole book is never compared to Kairos's top-50 hit rate.
What Kairos would have said
Scores are the model’s percentile at each company’s first observed funding event, not at a later round. That matches this fund’s entry only when the fund was in the first-round syndicate. A deal is flagged when its percentile clears that vintage’s top-50 cutoff. The whole book is not compared to the top-50 hit rate.
