MVP Development
for SaaS
— Checklist
A step-by-step MVP Development checklist for SaaS startups. Every action item is prioritized by impact, with clear owners and success criteria.
SaaS startups applying MVP Development face unique dynamics: competitive keyword landscapes, buyer education cycles, and the constant pressure to demonstrate ROI before renewal.
MVP Development checklist for SaaS startups
Scope Day (Day 0)
- Write a one-sentence problem statement: '[User type] who [problem] wants [solution] so they can [outcome]'
- List every possible feature — then cut everything that isn't required for the core value prop
- Draw the data model (entities, relationships) before writing any code
- Define your definition of done: what does 'shipped' actually mean?
Build Sprint (Days 1–4)
- Set up Next.js + Supabase + Tailwind + Vercel in Day 1
- Build auth and core data models before any UI polish
- Use AI coding assistance for boilerplate, tests, and repetitive logic
- Ship to a staging URL every day — never code without deploying
Production Audit (Day 5)
- Check all auth flows: signup, login, password reset, session expiry
- Validate all user inputs — never trust client-side data
- Add rate limiting to all API routes
- Test database queries under realistic load
- Verify environment variables are not exposed to the client
