Most SaaS products fail not because the idea was bad, but because the MVP tried to do too much. When you're building your first version, restraint is a feature. The four things every SaaS MVP truly needs are: one core use case that solves a real pain point, a dead-simple onboarding flow that gets users to value in under two minutes, basic authentication and billing infrastructure, and a way to collect user feedback automatically.
Everything else — advanced settings, integrations, analytics dashboards, team features — can wait. The goal of an MVP isn't to impress. It's to learn as fast as possible whether people will pay for your solution. Ship the smallest thing that delivers real value, then iterate based on what your first 50 users actually do, not what they say they'll do.
