Demand signals
Evidence that the problem exists and at what scale — from reviews, searches and community discussion.
Validating a business idea means answering three questions before spending real money: does anyone actually have this problem, is somebody already solving it, and can you reach the people who do. Most validation skips straight past all three and goes to “let us build a landing page and see”.
Talking to a few potential customers is the usual advice, and it is good advice — but it answers only the first question, slowly, and with a sample small enough that one enthusiastic conversation can carry a whole quarter. It tells you nothing about who already occupies the space or what they charge.
Segmentable answers all three from the market that already exists. It finds who has the problem and in what volume, who serves them today and how, what the going price is, and where demand is heading. The result is not a verdict handed down by a model — it is a structured picture with the evidence attached, so you can decide and defend the decision.
What you get
Who already solves it
The players occupying the space today, how they position and what they charge.
The segments worth serving
Which groups have the problem sharply enough to pay, and which merely have it.
Risks named specifically
What would have to be true for this to work, and where the assumption is weakest.
Market size for the idea
TAM, SAM and SOM derived from segment structure rather than from a headline figure.
A verdict you can defend
Take it or drop it, with the reasoning and the sources behind the recommendation.
How it works
Describe the idea in your own words
No framework, no template — a few sentences about what you want to build and for whom.
The system checks it against the market
Demand, existing players, pricing and trends are collected and structured.
You get an answer with evidence
A verdict, the reasoning and click-through to the source behind every claim.
What it looks like inside
Real product screens, not mockups.
Who it is for
Manager handed an idea from above
You have to take it on or turn it down with reasons, by a date that is already close.

| Time | A day | A week of asking around | 3-6 weeks | Minutes |
| What it checks | Demand, players, pricing, risks | Mostly demand | All of it, slowly | Whatever the prompt asked |
| Verifiability | Source behind every claim | Anecdotes | Cited selectively | None |
| Comparable across ideas | Same method every time | Depends who asked | Too expensive to repeat | Depends on the prompt |

Frequently asked questions
Can data really validate an idea?
It can rule one out cheaply and tell you what would have to be true for it to work. It cannot promise success — nothing can. What it removes is the class of failure where the answer was already public and nobody looked.
Does this replace customer interviews?
No, it sequences them. The check tells you which segments are worth talking to and what to ask, so interviews stop being a fishing expedition.
What if the answer is no?
That is the cheapest outcome available. An unwelcome answer with sources costs less than two quarters spent building toward it — and the report says which assumption failed, not just that it did.
How is this different from asking a chat?
A chat will validate almost any idea if you phrase it hopefully, and it cannot show you a single source. Here the answer comes from collected market material and every claim opens into the evidence.
How much does it cost to start?
A one-off Explore run starts at $79 and covers demand, segments, competitors and market size. Dollar checkout is not open yet, so we set the first run up with you directly.
Can I check several ideas and compare them?
Yes — that is the usual pattern for teams with a queue. Each idea goes through the same method, so the results are comparable instead of depending on who prepared them.
