Shipping paid MVPs in 7 days instead of 6 months

While exploring ideas and thinking through how I’d validate them, I kept running into the same friction:

• Agencies assume long roadmaps and ongoing retainers
• No-code tools work until you need real auth, payments, or custom logic
• Building solo often means spending months before knowing if anyone will pay

So I’m testing a very constrained approach called MVPin7.

The idea is simple:
Build a real, production-ready MVP in 7 working days — auth, payments, database, and one core feature only. No polish, no platforms, no “phase two.” Just enough to validate demand with real users.

Fixed scope, flat price, full code ownership.
If it can’t be built in 7 days, it’s probably not the right MVP.

I’m early and mainly looking for feedback from people who’ve tried to validate ideas quickly (or learned the hard way).

Keen to hear the community’s thoughts on this.
