How to build a SaaS MVP in 2026

Short summary

A SaaS MVP should be the smallest complete experience that proves users will pay for your solution, not a stripped-down version of your grand vision. The guide recommends scoping to one core job, choosing a boring managed stack like TypeScript with PostgreSQL and Supabase, building only the critical path from signup to value, and shipping within four to eight weeks. Common failure modes include over-engineering for scale, skipping the payment step, and polishing UI before validating the core assumption.

• •Scope to one core job expressed as a single sentence; cut features not quality
• •Use a boring managed stack and build only the critical path end to end
• •Ship in 4-8 weeks; validate payment intent early; do things that don't scale
