Its batch
Summer 2021 had 393 companies in YC's listing: 286 Active, 40 Acquired, 0 Public and 67 Inactive, so Zeit Medical is one of 67 companies from that batch listed as Inactive (17%). 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: Zeit Medical in the Y Combinator directory. Measured 2026-11-10 from Y Combinator's company directory.
