Problem-Solution Fit is the process of proving that your solution effectively addresses a real, urgent problem for a clearly defined user.
This happens before product-market fit — and it’s where many ideas go wrong. Teams often jump into building without deeply understanding the problem or confirming that their solution genuinely matters to users.
Validation includes user interviews, solution sketching, value proposition testing, and early feedback loops. The goal is to build confidence that the product idea is not just interesting — but necessary.
By investing in this step, companies save time, avoid unnecessary features, and reduce the risk of launching something nobody needs. It’s one of the most valuable stages in early product innovation — and one that separates successful startups from failed ones.
