Finding a co-founder · checked 11 November 2026

Start with people you have worked with; if there are none, go where co-founders look, like YC's Co-Founder Matching, and build together first.

YC's Co-Founder Matching is free and takes no equity, and founder meetups, TiE chapters, hackathons and alumni networks are where strangers become collaborators. Treat it like your most important hire: build something real together for a few weeks and talk through roles, money, equity and what happens if one of you leaves. Put founder vesting into the shareholders' agreement before you commit.
