SaaS MVP Development: How to Launch in 90 Days

Most SaaS founders spend too long building and not enough time selling. The 90-day MVP framework forces you to ship a real product to real users — fast. Here's how we've done it at SVB Tech Labs, and how you can too.

What is an MVP?

An MVP (Minimum Viable Product) is the smallest version of your product that delivers enough value for someone to pay for it. Not the smallest version you can build — the smallest version someone will pay for.

The key question: what is the one problem we solve so well that someone will give us money?

The 90-Day Framework

Days 1–10: Validate Before You Build

Don't write a single line of production code yet. Spend 10 days validating:

Interviews: Talk to 10–15 potential users. Ask about their current workflow, biggest pain points, and what they're paying today to solve this problem.

Landing page test: Build a simple landing page describing your product. Run ₹5,000 of Google or Meta ads to it. See if people sign up. No product needed.

Pre-sell: Can you get 3–5 people to pay for early access before the product exists? If yes, build it. If no, rethink.

Days 11–20: Nail the Scope

After validation, ruthlessly cut scope. For a 90-day MVP, you have time to build ONE core use case extremely well.

Ask: If a user could only do one thing with this product, what would it be? Build that — perfectly.

Create a simple spec document:

  • 3–5 core features (not 20)
  • User flows for each feature
  • Data model (what does your database look like?)
  • Tech stack decisions

Days 21–60: Build the Core

This is the 40-day build sprint. The golden rule: no gold-plating. Every feature must be functional, not perfect.

Our preferred stack for SaaS MVPs:

  • Frontend: Next.js + TailwindCSS
  • Backend: Node.js + PostgreSQL
  • Auth: Clerk or NextAuth
  • Payments: Razorpay (India) / Stripe (global)
  • Email: Resend
  • Hosting: Google Cloud Run

Focus on:

  1. Authentication (sign up, log in, password reset)
  2. Core feature #1 (the thing you pre-sold)
  3. Basic dashboard
  4. Payment integration
  5. Basic email notifications

What NOT to build yet:

  • Admin panel
  • Analytics dashboard
  • Team/multi-user features
  • Mobile app
  • Complex onboarding flows

Days 61–75: Beta Testing

Invite your 10–15 validation interview participants to use the product for free. Watch them use it (in person or via screen share if remote). You'll discover:

  • Features you assumed were clear that are confusing
  • Workflows you didn't anticipate
  • Bugs you didn't know existed
  • Features people ask for that you hadn't planned

Fix the critical bugs and confusion points. Ignore feature requests for now.

Days 76–90: Launch

Week 11: Set up your pricing page. Don't overthink it — one or two simple tiers. Charge enough to feel real.

Week 11: Write 3–5 SEO blog posts targeting keywords your users search for.

Week 12: Public launch:

  • Product Hunt
  • LinkedIn and Twitter announcements
  • Post in relevant communities (Reddit, Slack groups, WhatsApp groups)
  • Email your waitlist
  • Ask beta users for testimonials

The Most Common Mistake

Scope creep. Every SaaS founder wants to add "just one more feature" before launch. Resist this completely. A shipped product with 5 features beats a perfect product with 20 features that's still in development.

What Comes After 90 Days

After launch:

  • Talk to every single user who signs up
  • Track where users drop off (your funnel)
  • Fix the thing that's causing the most churn
  • Only add features that help retention

Revenue solves most early problems. Get to your first 10 paying customers before worrying about anything else.
