Built by a founder who lived the problem.

I started CofounderUp because I couldn't find what should have already existed.

I had an idea I cared deeply about. I spent months looking for someone to build it with. I asked everyone I knew. I tried the platforms. Everyone said yes, nobody actually showed up. The serious platforms felt closed. The open ones felt like noise.

Meanwhile, somewhere in this country, someone with the exact same problem was doing the exact same search. We should have already found each other.

That's the gap CofounderUp is built to close.

Not a networking site. Not a job board. Not a platform that matches you on skills alone. A place where serious founders find each other — built around the compatibility that actually makes partnerships work.

CofounderUp looks at how you handle risk, pace, conflict, and vision. Because the technical skill of your cofounder matters far less than whether you're actually compatible as people.

We're pre-launch. We're building this slowly and carefully, the way good cofounder relationships start — with intention.
