Its batch
Winter 2019 had 195 companies in YC's listing: 118 Active, 34 Acquired, 0 Public and 43 Inactive, so Hypnos is one of 43 companies from that batch listed as Inactive (22%). 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: Hypnos in the Y Combinator directory. Measured 2026-11-10 from Y Combinator's company directory.
