Use evidence when the decision matters.
Not the right fit
- You need statistically representative market research.
- You only want positive feedback to support a decision already made.
- No realistic potential customers can yet be identified.
Why this is different
AI tries to analyze your idea. We ask real customers.
AI can estimate market size, analyze competitors, and challenge your business model.
But it cannot replace direct conversations with the people who might actually buy your product.
We speak with those people and turn their answers into evidence you can use before spending months building the wrong thing.
How it works
From idea to evidence in five steps.
You tell us your idea
You explain the product, target customer, and the assumptions you want to test.
We find the right people
We identify 20 realistic potential customers in your target market.
We interview them
We speak with them directly about the problem, current alternatives, buying behavior, and willingness to pay.
We analyze the evidence
We identify repeated patterns, objections, demand signals, and the most important changes to make.
You make the decision
You receive a clear recommendation: build, change, or kill the idea.
What we are really testing
Not just if people like the idea.
We want to know whether the problem is important enough for a real buyer to act.
01
Problem severity
Is the problem painful enough to matter now?
02
Current behavior
How are customers solving the problem today?
03
Willingness to change
Would they seriously consider a better alternative?
04
Willingness to pay
Does the idea have credible commercial value?

Questions you may have.
What kinds of ideas can you test?
We focus mainly on B2B or B2C products, services, software, and research-based innovations where realistic potential customers can be clearly identified.
Why 20 interviews?
Twenty interviews provide a focused evidence base for identifying repeated themes and important disagreements. They do not prove market demand statistically, so the recommendation also explains the limits of the evidence.
Do you only interview people who already know us?
No. The goal is to speak with realistic potential customers, not only people already connected to your organization.
What do we receive?
You receive a report containing the main findings, demand signals, objections, recommended changes, and a clear build, change, or kill recommendation.
Test your idea
Let us ask the customers first.
Tell us what you are thinking of building, who it is for, and what problem it solves. We will get back to you personally.
