Problem-Solution Fit
Problem-Solution Fit
Evidence, usually from a small group of early users, that your specific solution relieves a real, previously validated problem. It is the checkpoint between "this problem is real" and "the market wants this at scale."
A handful of early users switching from their old workaround to your prototype, and staying switched, is a problem-solution fit signal.
Why it matters
It’s possible to validate a real problem and still build a solution that doesn’t fit it well. Problem-solution fit checks whether your particular approach, rather than just the problem space, is right before you invest in scaling it.
