The 12-Week MVP Framework
At **Inviro360**, we've helped launch **30+ SaaS products** from concept to paying customers. Our 12-week MVP framework is battle-tested and designed to maximize learning while minimizing waste. Here's exactly how we do it.
Weeks 1-2: Discovery & Strategy
Define Your Core Value Proposition
Every successful SaaS starts with a **single, clear problem** that it solves better than anything else. Don't try to build everything — identify the **one feature** that would make users pay.
**Questions to answer:** - What specific problem are you solving? - Who exactly is your target user? (Be specific — "marketing managers at B2B companies with 50-200 employees") - How are they currently solving this problem? - Why would they switch to your solution? - What would they pay for this solution?
Map Your User Journey
Create a simple user flow: **Sign Up → Onboard → Core Action → Value Delivered → Retention**. Each step should be as frictionless as possible.
Weeks 2-4: Design & Prototyping
Design System First
Before designing any screens, establish your **design system**: - Color palette (3 colors max) - Typography scale (heading + body) - Component library (buttons, inputs, cards, tables) - Spacing system (8px grid)
Key Screens to Design
For an MVP, you need exactly these screens: 1. **Landing page** — Explains value, drives sign-ups 2. **Onboarding flow** — 3 steps maximum 3. **Dashboard** — Shows the core value at a glance 4. **Core feature screens** — The 1-2 screens where users do the main action 5. **Settings/billing** — Account management and payment
Weeks 4-10: Development

Common MVP Mistakes to Avoid
- **Building too many features** — Ship the minimum that delivers value
- **Ignoring analytics** — You can't improve what you don't measure
- **Skipping design** — A poorly designed MVP repels potential customers
- **Premature scaling** — Don't optimize for 100K users when you have 10
- **Not talking to users** — Build feedback loops from day one
