In an effort to get more companies using Val Town, I wanted to see which of our existing userbase was part of a YC company.

I found this wonderful google sheet with all YC companies, and had Townie make me this interface to join it with an exported CSV of our users table.

All the compute happens client-side, so it's safe for you to run on your customer lists too.

If you want any changes, fork it & have Townie customize it for you. Feel free to send me a pull request or leave a comment :)
