Its batch
Winter 2018 had 146 companies in YC's listing: 77 Active, 29 Acquired, 1 Public and 39 Inactive, so Mighty Buildings is one of 39 companies from that batch listed as Inactive (27%). 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: Mighty Buildings in the Y Combinator directory. Measured 2026-11-10 from Y Combinator's company directory.
