If you are building something and want to test whether it is aimed at the right person, this guide walks you through it. You will use Optomize, the AI coach built on the 5 Spheres of Empathy method, to map your customer's real situation, find your early adopter, surface your riskiest assumptions, and turn their resistance into a brief you can build from. The whole sequence runs in one conversation. Work through the steps in order.
