Validation through real user behavior

People talk. But behavior tells the truth. This module teaches you how to run experiments that test whether users act on a problem. You'll build landing pages, fake features, and explainer videos to see if people click, sign up, or pay. Behavioral validation gives you the strongest signal: not opinions, not claims, but real-world action. Use it to pressure-test the most critical problems you've uncovered through qualitative and quantitative research.
