I'm Nathaji, founder of 50Fold. I've been a startup founder for 5+ years, during which I:
- Scaled a company from 0 to a $30M valuation as a solo founder
- Was accepted into 3 top accelerator programs
- Won multiple 1st-place hackathon prizes
I built 50Fold to help founders avoid the pitfalls I fell into. It's based on hundreds of hours of research and years of 0→1 startup experience.

Questions
I already have ChatGPT or a Claude Code subscription.
Keep it. ChatGPT and Claude tell you what to do. 50Fold knows what works, and does the work in your own tools. It also plugs into Claude, ChatGPT and Cursor, so your AI sees the same goal, tasks and results.
Will 50Fold tell me whether my idea will work?
It grades it: a grade, the basis for it, and what would raise or lower it. That's judgment, not a promise. Nobody can guarantee an idea will work, and 50Fold never does. Then it runs the work that tests demand, before you spend months building.
Will 50Fold build my app for me?
Yes, two ways. Your AI team can write the code in the 50Fold app, or hand the specs and plan to your own Claude Code, Cursor or Codex. Either way it's enterprise-grade from day one: auth, security, tests and monitoring, built to scale.
What do I need to bring?
The tools the work needs: the ones you already use, where they fit. Otherwise 50Fold recommends the best fit for your business and shows the cost first. They're your accounts; 50Fold sets them up and runs them.
How much of my time does it take?
A few minutes a day for decisions, plus your calls: interviews, sales or investors. 50Fold does the rest.
Who owns the code?
You do. 50Fold doesn't claim ownership of the code, docs or anything else your team makes for you. Your company brain is yours too.
What if I change my mind?
Full refund until 30 days after your early access starts. Refund policy
