Customer discovery is the practice of testing a startup's assumptions about its customers before building much, through interviews, observation and small experiments with people who might buy. Steve Blank made it the first step of his Customer Development method. It counts when what the team learns changes a product or market decision.

How Customer Discovery works
Learning before committing cuts the risk of building something nobody chooses. AppFolio's founders interviewed about 20 property managers and found interest dropped sharply whenever the product lacked accounting, so they built trust accounting in between 2006 and 2008. Talkspace tried group and individual video sessions that failed to convert, noticed users writing their problems to customer support, and launched unlimited text therapy in 2014.
Discovery takes founder time and the discipline to change plans when customers disagree with them.
