Customer Discovery

Most failed startups did not fail because the product was bad. They failed because nobody wanted what they built. Customer discovery is the discipline of finding out what customers actually want — before you invest months building it. This course teaches interviewing, validation, and the habit of testing assumptions early and cheaply.
