Y Combinator's directory lists 6,262 companies across 50 batches. Of those, 4,333 are listed Active, 825 Acquired, 23 Public and 1,081 Inactive. Newer batches have had less time to succeed or fail, so compare a batch with batches of a similar age: among batches from Summer 2005 to Winter 2024, 23% of companies are listed Inactive.
Statuses are Y Combinator's own listing in its public company directory, read on the date shown. YC's directory can drop companies altogether, so the Inactive counts here are a floor, not a full count of companies that stopped. Acquired and Public are as YC lists them; neither says anything about the price or the outcome for founders.

Shut down
The companies YC lists as Inactive, with the newest status changes first: YC companies that shut down.
How this is measured
Measured 2026-09-26 from Y Combinator's company directory. Each company is counted once, in the batch YC lists it under. A status change is recorded the first time the directory lists a company differently, so from 2026-09-26 onward this page can say when a company moved from Active to Inactive; before that date only the current status is known. Nothing here says why a company stopped: the directory does not record reasons, and neither does this page.
