The MVP Mindset

An MVP is not a buggy prototype. It's the smallest thing that validates your hypothesis while being good enough that users actually use it. Here's how to build one in 12 weeks.

Week 1-2: Foundation

Technology Stack Selection

Choose boring technology. Our recommended stack for most MVPs:

  • Frontend: Next.js + Tailwind CSS
  • Backend: Next.js API routes or Node.js
  • Database: PostgreSQL (or MongoDB for unstructured data)
  • Auth: NextAuth.js or Auth0
  • Hosting: Vercel + Supabase/Railway
  • Payments: Stripe

Development Environment

  • Set up CI/CD from day one (GitHub Actions)
  • Configure staging and production environments
  • Set up error tracking (Sentry)
  • Set up basic analytics (Mixpanel or PostHog)

Week 3-4: Core Feature

Build ONE core feature well. The feature that, if it works, proves your hypothesis.

  • No admin panels yet
  • No user settings pages
  • No email notifications (hardcode for now)
  • No multiple user roles

Week 5-6: User Journey

Complete the critical path:

  • Signup/login flow
  • Onboarding that leads to core feature
  • Core feature usage
  • Success state (user achieves goal)

Week 7-8: Polish Critical Path

  • Error handling on all critical flows
  • Loading states
  • Mobile responsiveness (if B2C)
  • Basic input validation

Week 9-10: Payment Integration

  • Stripe checkout integration
  • Subscription management basics
  • Invoice/receipt emails
  • Cancellation flow

Week 11: Testing & Bug Fixes

  • Manual testing of all user flows
  • Fix critical bugs only
  • Performance check (should load in under 3s)
  • Security basics review

Week 12: Launch Prep

  • Set up monitoring and alerting
  • Prepare customer support channel
  • Write minimal documentation
  • Create backup and recovery procedures

What NOT to Build

  • Admin dashboard (use database directly)
  • Complex permissions (one role for MVP)
  • Multiple integrations (one is enough)
  • Customization features
  • Perfect UI (functional > beautiful)
