Interest and purchase intent are not the same thing. People can find an idea genuine, ask real questions, and still not buy: not out of bad faith, but because "I like it" and "I pay" are different states, separated by friction that informal tests do not measure.
At Snowinch we see it when a founder arrives with apparent traction and zero conversions.
The signals all looked positive.
Payment did not.
The demo that "went well"
The demo went well. Better than well: questions, "when will it be available", "I would definitely use it", "finally something like this".
Then the product goes out, or even just the landing with signup, pre-purchase, a serious contact. Silence arrives. Not an explicit no. Not criticism. Only absence: the hardest form to read, because it says nothing precise and says everything at once.
This has a banal name: false positive of validation. It costs because it arrives after time, energy, often money already spent, and because the signals that preceded it all looked green.
The useful demo ends with a specific ask: a follow-up date, a formal commitment, "what would you value it at?". The reaction to that sentence says more than all the nodding before.
Why "nice idea" costs nothing
When you tell the idea to a friend, a LinkedIn contact, someone at dinner, saying yes is free. Saying no has a social cost: working out a critique, disappointing, owning a judgment on something you worked on.
"Nice idea" closes the conversation well for both. That is how low-pressure interaction works: people tend toward consensus, especially with people they know.
The context produces positive answers regardless of how much the market would pay. That is why informal feedback, used alone as proof, is almost useless: not because people lie, but because the setting is built not to surface the no.
Three scenes that confuse
An organic post with likes, comments, saves says something about the content, not about the product. People react to pieces they find interesting. Not necessarily to products they would buy. What counts is who clicks, leaves a real commitment, completes an action with a cost. Likes alone are not enough.
"I would definitely use it" is one of the dearest sentences a founder can hear. It sounds like proof. Then it is not. It describes a hypothetical intention, with no price, no alternatives on the table, no context in which they would change habit. The distance between "I would use it" and "I use it" is exactly the space where many digital products with good early feedback fall: pleasant demo, empty follow-up, silence at checkout.
A long waitlist is an interesting signal, not proof. People sign up out of curiosity, FOMO, support for someone they know. What counts is how many people answer intermediate communications, and how many convert into paying customers. A hundred involved people are worth more than ten thousand silent ones.
Where intent shows up
Willingness to pay is measured by putting real economic pressure into the process, as early as possible.
Pre-sale: offer the product at a reduced price, or even at full price, before it is finished. Someone who buys something that does not exist yet, with card or transfer on the table and no "when it is ready" excuse, is expressing a preference with real cost. It is the cleanest signal we have seen work.
In discovery conversations, bring price onto the table: "this will cost X, interested in talking about how it would work for you?". The answer to that sentence is more informative than the generic "would you like to use something like this?".
Showing existing alternatives (even worse ones, even manual) and asking how much they would pay for a better solution says something precise about perceived value and the real threshold.
In many cases it makes sense to offer the result the product will produce, by hand, for pay, before you build it. Someone who pays for the manual result is a serious candidate for the product. Someone who does not pay for the manual result will not pay for the app, no matter how well built it is.
Actually, thinking again: the jump between "I like it" and "I pay" does not deserve a six-step workshop scale. It is concrete friction. If you do not put money or serious time on the table, you are still measuring social consensus.
The optimism that masks silence
There is a bias that amplifies the problem: founders remember the yeses and reinterpret the silences. It happens without bad faith. It is a documented mechanism, and it hits even people who are lucid about the rest.
The internal narrative on "how it is going" gets built on favorable signals. Every interest becomes confirmation. Every missed conversion becomes a timing or landing problem, not a market problem. The absence of a no gets read as a yes.
The only antidote I know is to structure tests so the negative signal is visible, and to decide in advance which threshold of negative evidence (how many silences at follow-up, how many explicit price refusals, how much waitlist that no longer answers) would change direction before the internal narrative absorbs everything.
The positive feedback you already have is not trash: it tells you about the problem, the language, the features that seem relevant. What it does not do is tell you whether people will pay.
If likes are still enough
If likes, enthusiastic demos, and long waitlists are still enough for you as market proof, look elsewhere. If you want someone to celebrate informal consensus as traction, that is not us.
If you already have silence at checkout (or suspect it is coming) and need to put price, pre-sale, or a manual service on the table before building more, the rest is concrete: perimeter, threshold, first test with a possible no.
