Its batch
Summer 2020 had 209 companies in YC's listing: 122 Active, 42 Acquired, 1 Public and 44 Inactive, so Letter is one of 44 companies from that batch listed as Inactive (21%). 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: Letter in the Y Combinator directory. Measured 2026-11-10 from Y Combinator's company directory.
