Most product ideas sound better in a deck than they do in front of a buyer.

Prototype-led market validation changes the conversation. Instead of asking people to imagine a product, you show a focused surface, explain the workflow it owns, and watch what kind of signal comes back.

The artifact can be simple: a landing page, a clickable prototype, a demo workflow, a productized service mockup, or a small working tool. The point is not to pretend the product is finished. The point is to make the promise concrete enough that the market can react.

Good validation looks for buyer pull, not compliments. Who wants the thing badly enough to take a call, join a pilot, share data, push for budget, or explain what would make it useful on Monday morning?

That signal gives the team a cleaner decision: kill it, refine it, pilot it, or productize it.

Turn the hypothesis into a scoped build

Use the Canadian MVP scoping guide and free brief to define the user, core flow, exclusions, and acceptance criteria. Bring that brief into a prototype sprint when there is a concrete question the first version can answer.
