Who actually runs YC — partner ranking & per-batch load
YC group partners assigned via the 'Primary Partner' field scraped from each company page. Coverage is 80.7% — older batches (W22-S23) and inactive company pages don't expose the field. Where the data is clean (W25-F26: ~100%), every YC company has exactly one accountable partner. This is the org chart behind the dealflow.

attribution coverage
Caveat
Partner attribution is most reliable for W25 onward (95-100% coverage). Older batches have ~50-80% coverage because YC removes partner listing from pages of inactive/acquired/dead companies. Treat older partner totals as floors. Mean companies-per-partner is computed only over attributed companies.

What the partner data tells us
YC's dealflow runs through ~17 group partners. The top 5 (Friedman, Flora, Dessaigne, Alstromer, Blomfield) have each personally signed off on 200+ YC companies — that's ~50 companies/year/partner, sustained for 4 years. With ~10-15 companies per partner per batch and 2 batches/year before quarterly format, this is consistent. Specialisation by RFS theme is real but partial — most partners span 5+ themes. The 'Primary Partner' system is YC's load-balancer: each company gets one accountable human, but the partner pool is far smaller than the founder pool. That's why partner taste, not RFS labels, is what actually drives selection decisions.
