A SaaS MVP timeline often starts slipping, typically because of unclear scope.
Founders may enter development with a product vision instead of a clearly defined first release. As new roles, workflows, integrations, and “small” features are added, the amount of work grows while the original deadline stays the same.
That is scope creep, where project requirements expand without a matching increase in time, budget, or resources. So, for an MVP, the question is now, What is the smallest launchable product that can prove the core value?
Y Combinator makes a similar point around launching the smallest version that lets founders start learning from real users instead of trying to build the complete product first.
If you are still defining that first release, our SaaS MVP Development Guide breaks down scope, cost, features, and launch planning in more detail.
