Interest is attention that costs the buyer little or nothing. Demand evidence becomes stronger when a buyer puts something meaningful at stake.
When traction stalls, it is tempting to assume the product is the problem. This page sets out six traction signals and what each one can point to, what interest, signups, interviews or a waitlist actually prove, and a two-minute self-check for the evidence you already have.

Stalled traction is a symptom, not a single problem. It can point to the buyer, the offer framing or the channel, as well as to the product.
Assuming the product must change can be expensive. Roadmap pivots, engineering sprints and new features do not help if the gap is commercial.
A useful first step is to read the evidence you already have: which of the signals below is present, and what your buyers have actually done. The self-check further down helps with the second question.
Each signal is a symptom, not a diagnosis. It can point to where in the commercial motion to look first.
People are reaching the product, but few convert. This can point to the offer framing, the buyer segment or the pricing rather than the product itself.
This can indicate that the person you are reaching feels the pain but lacks the authority or budget to buy, or that the conversation has not moved beyond intent.
A demo attended and praised is interest, not commitment. Stronger demand evidence appears when the buyer puts something at stake, such as a paid pilot, a signed order or formal procurement.
This can point to a gap between what the buyer expected at purchase and what the product delivers first, which can be an onboarding or offer-alignment question.
This can indicate that an early warm audience, such as early adopters, network connections or one community, is running out, so the next buyers cost more to reach.
Users can like a product without paying more, referring others or expanding their usage. This can point to a problem that is real but not urgent enough to change buying behaviour.
Demos attended, trials started, emails answered and waitlist signups can all feel like traction. A waitlist shows attention; what matters is what those people do when price, terms or a dated next step become real.
Thirty interviews can feel like validation. But praise, interest, intent and commitment are not the same signal. Grade what people actually did, not how many interviews or conversations you have had.
Politeness → Interest → Intent → Commitment
GTM Right's working rubric, not a universal research taxonomy.
Positive words with no meaningful action or stake. The person may like the idea, want to be supportive, or agree the problem exists.
"That sounds really useful. I think people would want this."
The person gives attention or a low-cost signal - joins a waitlist, leaves an email, asks for an update or requests a demo - but has not faced real price, effort or terms.
"Send me the link when it is ready. I would like to try it."
The buyer moves toward a decision: asks about price or terms, brings in a decision-maker, agrees a dated next step, requests a proposal or starts a procurement or pilot conversation. Stronger than interest, but still reversible.
"If you can solve X within this budget, send me the proposal and I will bring finance into the next call."
The buyer puts something scarce at stake - money, a paid pilot, a deposit, a signed order, formal procurement, allocated internal resource, or another consequence they would notice if they walked away.
"Send the invoice. We can start on 1 October."
Compliments, signups, letters of interest or free use can look positive without proving meaningful purchase commitment.
Which grade best describes the strongest repeated behaviour?
Choose a grade to see what that evidence proves, what it does not prove, and the next stronger test.
A non-binding letter of interest or free usage is not automatically commitment simply because it is formal or measurable.
Do not turn this into a numerical score. The purpose is to identify the next missing proof.
Old interview notes can contain useful evidence, but compliments and hypothetical answers should not be read the same way as observed behaviour or commitment. Re-read what you already have before running another round of interviews.
Conversation count does not determine evidence strength.
Separate what the buyer said about the idea from what the buyer actually did.
Keep these notes, but do not read them as observed behaviour or commitment.
Look for the most recent real occasion the problem happened, rather than a general opinion about it.
If no one could describe a recent occasion, record that as well. It is evidence too.
Write down what the buyer does about the problem today.
Living with the problem is a workaround as well, and often the one you have to beat.
Write down what the problem costs the buyer, as they stated it or showed it.
Record only a consequence the buyer stated or demonstrated. Do not infer a cost they did not state or show.
Write down anything the buyer gave up or committed, however small.
A pilot that costs the buyer nothing leaves the price question untested. The evidentiary weight of an LOI depends on its actual terms and binding status; the document label alone is not the same as payment. A promise to pay is not payment, and one commitment is evidence, not proof of repeatable demand.
Note where what buyers said and what they did pull in different directions, then name the strongest behaviour that repeats across them.
Finish with the strongest behaviour that repeats across buyers, not the most encouraging single comment. Do not average different kinds of evidence into a number.
The re-read gives you evidence. The four-grade rubric above interprets how strong the buyer signal in it is: Politeness → Interest → Intent → Commitment.
This is an editorial way to re-read founder-held evidence. It does not authenticate the notes, turn an interview into independently verified market evidence, or establish buyer budget, willingness to pay, repeatability or commercial viability.
Once you have graded the evidence you already hold, the free Stage 1 check looks at public market evidence for the problem. Usually under 90 seconds.
True Validation tests public market evidence only: whether the problem is real, visible and urgent. It does not prove buyer budget, willingness to pay, offer fit, acquisition economics or full commercial viability.
Stages 2 to 6 test the later commercial assumptions: Buyer Precision, Buyer + Offer, Revenue Funnel, Market + Funnel, Commercial Decision. They do not change the fact that Stage 1 is market validation only.
