Before we start any validation work with a founder, we ask one question:
"If your product disappeared tomorrow, what would your target customer use instead?"
The answer to this question tells us more about the viability of the idea than any amount of market research.
If the answer is "nothing — they would just go without" that is a strong signal the problem is a nuisance, not a pain. People tolerate nuisances. They pay to solve pain.
If the answer is "they would go back to doing it manually with spreadsheets and it would cost them significant time and money" that is a signal of genuine pain and an existing budget allocation. There is money being spent on an inferior solution. That money can move.
If the answer is "they would use [specific competitor] but it does not do [specific thing]" that is the clearest possible market signal. There is established demand. There is a documented gap. The question is whether you can fill that gap better than the incumbent.
The rest of the validation process is about confirming or challenging the answer to this first question. The twenty interviews, the smoke test landing page, the pre-sale conversation all of it is evidence for or against the hypothesis the first answer surfaces.
The founders who skip validation are not skipping a process. They are skipping the information that determines whether the build is worth doing.
