An AI cofounder, not a chatbot
AI code-gen collapsed the cost of building your product. Finding customers, telling your story, and closing deals hasn't moved. Cofounder does that work with you — and gets sharper about your business every week.
Built for technical solo founders shipping their first commercial product.
A partner that collaborates on the business — and leaves the founding of you to you.
The gap
Cursor, Claude Code and the rest made you a one-person engineering team. But marketing, positioning, outbound and follow-up are still a full-time job you don't have time for — and the validate-and-distribute barrier is exactly where first products die.
What it does today
Turns your foundation into a real content engine.
Finds the right people and runs the outreach.
Coming next
Validate what to build and shape the roadmap from real signal — before you write the code.
Track runway, unit economics and pricing so you always know if it pays.
Why it's different
Most tools forget. Cofounder runs on a shared memory substrate, so every agent's work makes the others smarter about your business — not software in general.
