FAQ

YC companies list questions

How many companies has Y Combinator funded?

The public yc-oss dataset, updated October 4, 2026, lists 6,269 launched YC companies: 4,331 active, 829 acquired, 1,086 inactive and 23 public. The biggest batches were Winter 2022 (398 companies), Summer 2021 (391) and Winter 2021 (335).

What is in the YC companies list?

One row per company with name, website, batch, status, industry and team size, plus founders. Founder emails are added where we find one and it passes a live SMTP check; rows without a verified email say so instead of guessing.

How much does the YC startup database cost?

$19 for one batch, $49 for all 4,331 active companies, $69 for every YC company ever, including acquired and inactive ones. One-off payments through Stripe, no subscription.

Can I order a single YC batch?

Yes. Choose the one batch option and type the batch name in the order form, for example Summer 2025. You can also add an industry filter such as B2B, fintech or healthcare.

How do you find founder emails?

The Getlead team matches each founder to our database of 177M+ people records and public sources, then checks every address with a live SMTP handshake. Verification lowers bounces but does not guarantee delivery.

Why not just use the YC directory?

The directory is great for browsing one company at a time. It does not hand you a spreadsheet with founder emails ready for a CRM, which is what this list is for.

Is Getlead affiliated with Y Combinator?

No. This is an independent list built from public information. Getlead is not affiliated with, endorsed by or sponsored by Y Combinator.

Need one founder's address only? Use the email finder.
