How to use this list
- Filter by industry, listed location or status, or search for a company, a city or one of YC's tags.
- Each name opens the company's YC profile. The website link goes to the company's own site; we show it only for companies YC lists as active or public, because the domains of closed and acquired companies often lapse or change hands.
- Status is YC's label, not our assessment. Active does not mean funded, growing or looking for suppliers.
- Keep a list as you go. Add to my research saves a company in this browser, and Download my list turns your picks into a spreadsheet.

About this data
Each record comes from YC's public startup directory, through the open-source yc-oss mirror of it, pulled on September 13, 2026. We show YC's own industry, location and status labels and none of YC's company descriptions. The directory lists launched companies YC shows publicly, so a company that has left it will not appear here.
If a record is wrong, use Suggest a correction on its row and include a source. We check corrections against YC's directory and the company's own site.
