How to Build a SaaS MVP in 3 Months: A Technical Roadmap
Building a SaaS MVP in three months is ambitious but achievable with the right approach, technology choices, and scope discipline. This roadmap has guided dozens of successful SaaS launches, from productivity tools to vertical B2B platforms. The key is ruthless prioritization—your MVP should validate your core value proposition with the minimum feature set possible.
Month 1: Foundation and Core Features (Weeks 1-4)
Week 1-2: Finalize your MVP scope ruthlessly. Define your single core value proposition and the 3-5 features absolutely required to deliver it. Set up your tech stack—we recommend Next.js or React for frontend, Node.js or Python backend, PostgreSQL database, and Vercel/Railway for hosting. Implement authentication using Auth0, Clerk, or NextAuth rather than building from scratch. Week 3-4: Build your core feature—the one thing that solves your user's main problem. For a project management tool, that's task creation and assignment. For analytics SaaS, it's data ingestion and basic visualization. Resist adding 'nice-to-have' features. Deploy a working (even if ugly) version to staging by week 4.
Month 2: Polish, Payments, and User Management (Weeks 5-8)
Week 5-6: Integrate Stripe for subscription billing. Implement tiered pricing (start simple—free trial plus one paid tier). Build basic user management: signup, login, password reset, email verification. Add team/workspace functionality if your product is B2B. Week 7-8: Create your admin dashboard to monitor users, subscriptions, and system health. Implement basic analytics (Mixpanel or PostHog) to track user behavior. Focus on making your core feature polished and bug-free rather than adding new features. Conduct internal testing with your team and fix critical issues.
Month 3: Beta Launch and Iteration (Weeks 9-12)
Week 9: Launch private beta to 10-20 early adopters. These should be people in your target market who've agreed to provide feedback. Implement basic error tracking (Sentry) and monitoring (Datadog or Grafana). Week 10-11: Gather intensive user feedback through interviews and usage analytics. Focus on one question: Does the core feature solve their problem well enough that they'd pay for it? Fix show-stopper bugs and improve UX based on feedback, but resist adding new features. Week 12: Launch publicly. Set up customer support infrastructure (Intercom or basic email support). Prepare onboarding emails and documentation. Start your marketing engine. By the end of month 3, you should have 50-100 signups and ideally your first 5-10 paying customers.
Essential Technical Decisions for Speed
Technology choices that accelerate MVP development: Use managed services for everything non-core (authentication, payments, email, hosting). Choose popular frameworks with strong ecosystems (Next.js + Tailwind, Django + React). Start with monolithic architecture—microservices add complexity you don't need at MVP stage. Use Postgres for your database—it scales further than you'll need for MVP and has strong ecosystem support. Deploy on platforms with zero-config scaling (Vercel, Railway, Render). The goal is to spend 80% of your time on your unique value proposition, not reinventing solved problems.
