Where MVPs stall
- Months of building before a single user signs up
- A prototype that can’t take real customers
- Billing, roles and security left for “later”
- Freelancers leave and no one understands the code
What the programme fixes
- A live product in eight weeks, not eight months
- Auth, tenants and billing done properly from day one
- Analytics that show what users actually do
- Clean, documented code your next hires can own
Everything an MVP needs to take real money.
