Its batch
Summer 2008 had 22 companies in YC's listing: 1 Active, 4 Acquired, 0 Public and 17 Inactive, so Treehouse is one of 17 companies from that batch listed as Inactive (77%). Across YC batches at least two years old, 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.
The record: Treehouse in the Y Combinator directory. Measured 2026-11-10 from Y Combinator's company directory.
