“All AI application Startups in YC 23, 24, and 25 that now have more than 10 employees”

A broad-definition screen of eight Y Combinator batch tables (W23 through S25), as of 2026-09-03: 28 active AI-application companies list a current team above 10 people. Listed team sizes run from 11 (Capitol AI) to 105 (Campfire); no qualifying S25 company was found.

The four largest listed teams are Campfire (S23, 105), Avoca (W23, 85), Bland AI (S23, 65) and Artisan (W24, 50) — together over a third of all headcount on the list. vcbacked.co

Summer batches concentrate the qualifiers: S23 and S24 each contribute 7 of the 28 companies, half of the whole list. vcbacked.co

The most recent scanned batch, S25, produced no company past the 10-person threshold; F24 and X25 produced one each (Cekura and Auctor). vcbacked.co

San Francisco dominates: 18 of 28 companies list an SF address; the rest span New York, London, Berlin, Bengaluru, Bogotá and Washington DC. vcbacked.co

Screen of eight YC batch pages (W23, S23, W24, S24, F24, W25, X25, S25) at vcbacked.co, taken 2026-09-03; 28 rows, one per company. “AI application” is a broad researched definition — agents, copilots, vertical AI software, AI-native workflows and AI-powered end-user or business products — excluding hardware, robotics, foundation-model infrastructure, raw data APIs and drug discovery. Team figures are the source's listed “Team” values, not audited payroll; where duplicate domains showed differing values the higher current one was kept. A few classifications (Clueso, Casca, Brighterway, Cartage, Cekura) are broad calls.
