Your AI Startup Prenup, drafted in seconds.

Answer a few alignment questions with your co-founder. Our AI turns them into a clear draft for equity, vesting, roles and leaver terms — the conversation most teams avoid until it's too late.

  • • 4-year vesting & 1-year cliff by default
  • • Built from both founders' real answers
  • • Bring it to a lawyer instead of starting from zero

Frequently asked questions

Is Co-Found free to use?

Yes. Creating a profile, browsing, connecting, team chat and Sunday Live are free. Pro and Deluxe add more projects and AI tools.

What is the AI Startup Prenup?

A guided alignment draft covering equity, vesting, roles and leaver terms, built from both founders' answers. It's a discussion draft, not legal advice.

Can I build and launch solo?

Absolutely. Use the private workspace on your own — roadmap, Lean Canvas, AI tools — and launch your game, app or SaaS without a co-founder.

How does Sunday Live work?

Every Sunday 19:00–20:00 Stockholm time, members swipe through each other in real time. Mutual likes open a chat instantly.

How do Launches work?

Any project can be shown on Launches with a screenshot, video and link. A 7-day spotlight costs $19 and teams can split the cost.

Are private projects kept private?

Yes. Your team chat, tasks and notes are only visible to project members, even if you launch the product publicly.
