How to Build a SaaS MVP in 6 Weeks (Without Cutting Corners)

Most SaaS MVPs fail not because of bad ideas, but because of bad scoping. Teams try to build everything at once, run out of budget, and never launch.

Here's a framework I've used to ship multiple MVPs in 4-8 weeks.

Week 1: Scope Ruthlessly

The goal is to find the one thing your product does that creates enough value for someone to pay for it. Everything else is a future feature.

Ask: "If this product could only do one thing, what would it be?"

Week 2: Architecture & Design

• Choose boring technology (Next.js, PostgreSQL, Vercel)
• Design the core user flow — not every screen
• Set up CI/CD from day one

Weeks 3-5: Build the Core

Focus on three things:

1. The core value proposition feature
2. Authentication and basic user management
3. Billing (even if you start with manual invoicing)

Week 6: Launch & Learn

Ship to real users. Not a landing page — the actual product. Use their feedback to decide what to build next.

Common Mistakes

• Over-engineering the backend — you don't need microservices for 10 users
• Skipping billing — if people won't pay, you need to know now
• Premature optimization — make it work, then make it fast
