Start with Demand
Define a buyer in a specific situation, the problem they are already trying to solve, the alternatives they use, the desired result, urgency, and evidence that the problem is active.
Shape one clear Offer
Choose one outcome and the shortest believable path to it. Decide the delivery format based on the buyer and transformation—not because a course, ebook, or membership happens to be easy to create.
Make the Message testable
Explain who the product is for, what changes, how the approach works, why it is credible, and what the buyer should do next. Avoid unsupported income or performance promises.
Validate before expanding
Use the smallest credible test that exposes real behavior. Depending on the product, that may be conversations, a concierge version, prototype, live workshop, application, preorder, deposit, or a focused landing-page test.
Build the minimum worth delivering
Once the riskiest assumptions have better evidence, build the smallest version that can deliver the promised outcome responsibly. A minimum product should be reduced in scope, not careless in quality.
Turn the research into a product decision.
The Sellable Product Method connects Demand, Offer, and Message before the heavier build starts.
