Problem-solution fit explained
Problem-solution fit is the first milestone on the path to product-market fit. It answers a fundamental question: does your solution actually solve the problem you've identified?
Many startups build solutions looking for a problem. The most successful ones start with a deep understanding of the problem — who has it, how painful it is, and how people currently work around it.
Our checker evaluates the alignment between your stated problem and proposed solution, identifying gaps, assumptions, and areas where the fit could be stronger. It's a thinking tool that helps you refine your thesis.
