From the founder

Who it's for

“People who built an app with ChatGPT or Claude and need sign-in, payments and a domain to run it as a business.”

Why I built it

“AI can write the app, but sign-in, Stripe payments, per-customer data and a domain are the hard part. Gemmein runs those.”

— S. Ahmed, founder of Gemmein

Who it is for

Small studio owners, such as a yoga studio, who want to run bookings and payments without a developer.
Founders and solo builders who use ChatGPT or Claude to create and run their own web or mobile app.
Developers using coding tools like Claude Code, Cursor or Codex who want sign-in, payments and hosting handled for their app.
