Y Combinator's directory lists 22 companies in the Summer 2008 batch: 1 Active, 4 Acquired, 0 Public and 17 Inactive. 77% of Summer 2008 is listed Inactive, against 23% across YC batches at least two years old, so this batch has lost more companies than most.

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.

How this is measured
Measured 2026-09-26 from Y Combinator's company directory. Team size is the number YC lists for the company, where it lists one. Survival here means listed Active; Acquired and Public are shown separately because YC's listing does not say whether an acquisition was a good outcome.
