Problem-Solution Fit

/ˈprɑː.bləm səˈluː.ʃən fɪt/

A problem-solution-fit occurs if a startup has proved both: 1) that there is a 'problem worth solving' for one or more clearly defined customer groups, and 2) that there is evidence that these customer groups would consider the value proposition of the solution the firm proposes.

Having reached problem-solution fit means that you’ve understood your customers’ needs/ jobs-to-be-done and their desired outcomes. It also means that you’ve created a solution that addressed these needs in a unique way, as customer feedback suggests so (validation of desirability). However, contrary to widely-held opinion it does not mean that you already have evidence that they would really buy it. This next inflection point in lean validation is called product-market fit.
