Questions

How are the odds calculated?

A statistical model trained on the public YC directory. We took snapshots from October 2024 to February 2026, recorded which then-active companies were acquired by October 2026, and learned which profile features went with acquisitions: years since YC, team size and how it changed, sector, tags, location, hiring, and recent acquisitions in the same sector.

How accurate is it?

Modestly, and we show the numbers. Tested on companies it never saw, it ranks an acquired company above a non-acquired one about 63–67% of the time (AUC 0.63–0.67; a coin flip is 0.5). Companies in its top 250 were acquired about twice as often as average. Public directory data can’t see revenue, funding or talks, so treat the odds as a base rate, not a tip.

What is the signals brief?

For any company, ExitOdds reads its website and YC profile, Contextrie picks the passages that matter for an acquisition, and the brief lists signals for and against, each quoting its source. Quotes we can’t find in the source are flagged.

Is this affiliated with Y Combinator?

No. ExitOdds is an independent project using the public YC company directory (via the open yc-oss dataset). Nothing here is investment advice.

What do I get for free?

The top 50 of the ranking, 3 searches, and every company’s page with its odds and reasons, plus 3 signals briefs a day. A one-time $0.99 unlocks the full ranking with filters, CSV export and unlimited briefs, forever. No subscription.

Can I build something like this?

Yes. It runs on Contextrie (open-source context and state) and Bref UI (open-source interface). Both are on GitHub.
