Find the cofounder your startup is missing.
Post what you're building. Meet the people who can build it with you.
How it works
Three steps from idea to co-founder.
01
Founders post what they're building
Share your idea, the stage you're at, and exactly the kind of co-founder you need — whether that's a technical partner, someone to run operations, or an investor who believes in the space.
02
Co-founders and investors browse to find their fit
Filter by sector, stage, or role. Bookmark the ones that excite you. Every listing shows what's being built, what problem it solves, and what's on the table — so you can decide before you reach out.
03
Both sides connect and decide for themselves
Message directly — no middleman, no algorithm deciding your fate. Cofoundr makes the introduction. What happens next is up to you.
