YC companies that shrank this year

YC's public directory lists 6,376 launched companies across 50 batches since 2005: 4,406 active, 839 acquired, 23 public and 1,108 listed as inactive.

The newest batch with companies in the directory is Fall 2026 (219 companies). YC has also started listing Summer 2027 (1) and Winter 2027 (9). YC runs four batches a year: Winter, Spring, Summer and Fall.

By people listing them as their employer on public profiles (which can include contractors, drivers and hosts): DoorDash (84,144), Instacart (25,483), Stripe (16,694), Rappi (15,009) and Deel (9,642). 23 YC companies are public and 839 were acquired. Sort the table by Largest team to see the rest.

We found job postings in the last 60 days for 719 YC companies, led by Stripe (659 roles), EquipmentShare (262 roles) and Relativity Space (244 roles); another 1,017 say they are hiring on YC's directory. See YC companies hiring the most, or filter by Hiring for (engineering, sales and more). We count distinct role titles, because the same job is often posted on several job boards.

Ranked by team growth over the last 6 months, among active companies with 10 or more people: Human Archive (+579%), Freya (+355%) and Linewise (+331%). See the fastest growing YC companies, or open any batch and pick Fastest growing.

Team is the number of people who list the company as their current employer on public professional profiles, counted by Crustdata every month. It can differ from a company's own number (contractors, people who have not updated their profile). The 6 and 12 month changes compare that count with the same count back then, and we only show a change when the team had at least 5 people at the start.

1,108 companies are listed as inactive in YC's directory, which usually means they shut down or stopped operating. Filter the table by Status, Inactive to see them. YC does not publish why a company became inactive, and some inactive companies were acqui-hired.

Use Export CSV above the table. It downloads whatever you are looking at (a batch, a list, your filters and search) with domain, batch, status, team size and change, open roles, funding, investors and founders with their profile links. It asks for your email once; we never send anything to it.

The list of companies, batches, industries and locations comes from Y Combinator's public directory, via the open yc-oss dataset. Team size and growth, open roles, funding and founders come from the Crustdata API, which tracks 60M+ companies and 1B+ public professional profiles, and job postings. Each company is matched by its website and its name; 945 companies have no Crustdata record yet and show YC's data only. Funding is reported funding (including debt in the total) and can be incomplete.

Every week. The last update was on November 9, 2026. Founders are refreshed monthly. New companies appear the week YC adds them to its directory.
