Y Combinator Co‑Founder Matching

Where savvy founders go to meet potential co‑founders

(Actual founders who met on this site
and got funded by YC.)

We know even the best founders don't always have people in their network who are ready to start a company

That’s why we built co-founder matching.

Good for all stages

Whether you’re getting to know people for the future, or ready to go now.

Come with or without an idea

From YC companies who met on co-founder matching

Without this we never would have met, done YC, or started this company.

The YC Co-Founder Matching platform is a huge unfair advantage to filter for the exact people you’re looking for and save time on the search. It’s changing the game and enabling more people to start companies.
Philip and Mathias

Finding the right co-founder was always the biggest barrier preventing me from jumping in to start my own company. YC Co-Founder Matching felt like a cheat-code to solving that problem. Once we matched, we started working together every day and haven’t stopped since. Couldn’t be more grateful for Co-Founder Matching!
Andrew and Shreya

This was by far the most valuable tool I had access to when making the most important decision for my company. The quality and quantity of people who are serious about their venture and serious about looking for a co-founder was unmatched. We’re extremely grateful to YC Co-Founder Matching for bringing our founding team together.
