Y Combinator's directory lists 94 companies in the Fall 2024 batch: 89 Active, 2 Acquired, 0 Public and 3 Inactive. Fall 2024 is less than two years out, so its Inactive share (3%) is not yet comparable with older batches (23% across batches at least two years old).

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.
