The ability to build is not evidence of demand. That distinction has always mattered, and AI has just made it the most expensive mistake in business.

Anyone can now produce a working prototype, a course, a newsletter or a credible website in days. What no tool can produce is proof that enough people want it, will pay for it, and can be reached economically. The build got cheap. The market didn't get any less demanding.

This post gives you five questions to validate demand before you build, why each one matters, and the evidence behind them. Answer all five honestly and most of your marketing strategy writes itself. Fail to answer them and no launch plan can save you.

Why Building First Is the Expensive Way Around

Theodore Levitt named this failure decades ago in Marketing Myopia: businesses become vulnerable when they define themselves by the products they make rather than the customer needs they serve.

The danger is sharper now because the sequence has inverted. It used to take months and real capital to build something, which forced at least some market thinking before the build. Today a product can exist before the market has been understood at all. Speed makes myopia cheap to act on and expensive to discover.

The pattern shows up everywhere: a product that is technically impressive but solves nothing urgent, a website that looks credible but gives no one a reason to visit, an email sequence that runs perfectly while promoting an offer nobody particularly wants. Each of these is a demand-validation failure wearing an execution costume.

The Five Questions That Validate Demand

Run these before the next product, course, service or campaign. They are sequenced deliberately: each one only matters if the previous one passes.

1. Do enough people experience this problem?

Not “would people find this useful”, but: is the problem frequent enough, painful enough and widespread enough that people would change their behaviour to solve it? A problem that prompts a nod is not a problem that prompts a purchase. Look for evidence of people already spending money, time or workarounds on it.

2. Are they dissatisfied with the current alternatives?

Every real problem already has a solution in place, even if that solution is a spreadsheet, an agency, or ignoring it. Your competition is whatever people do now. Dissatisfaction with the incumbent, not the elegance of your alternative, is what creates switching energy. In B2B this bar is high: purchases involve multiple stakeholders and carry professional risk, so “slightly better” rarely moves anyone.

3. Can you reach them economically?

A large potential audience that cannot be reached at sustainable cost is not a viable market. Before building, name the two or three channels you believe are repeatable (not lucky) routes to these buyers, and estimate what it costs to acquire one customer through each. If the honest answer is “we'll figure out distribution later”, the validation has failed at this step.

4. Why would they trust an unfamiliar provider?

Existence is not credibility. Buyers rely on memory, familiarity, recommendations and what is easiest to justify to colleagues. A new brand starts with none of these. What will earn trust before the first sales conversation: evidence, guarantees, association with known institutions, a body of genuinely useful public work? If you cannot name the trust mechanism, you are asking strangers to take a professional risk on your behalf.

5. What will make them think of you when they finally enter the market?

This is the question most validation frameworks skip, and the evidence says it is decisive. Research from the Ehrenberg-Bass Institute, popularised as Professor John Dawes' 95:5 heuristic, shows that in many B2B categories the large majority of potential buyers are out of market at any given moment. You cannot convert them today. You can only be remembered by them. If your plan reaches only in-market buyers, you are competing for the smallest slice of your category while your future pipeline goes unbuilt.

What Validation Does Not Require

Validation is not a six-month research project, and it is not an excuse to never ship. It requires honest answers, gathered cheaply: conversations with real buyers, evidence of existing spend on the problem, a test of whether anyone responds to the proposition before the full build. AI is genuinely useful here, for synthesising research, pressure-testing assumptions and drafting test materials quickly. What it cannot do is take responsibility for the answer. Evidence informs. Judgement decides.

Ready to Build the Judgement Behind the Questions?

The five questions are simple to ask and hard to answer well, because answering them well is marketing: understanding markets, buyers, value and routes to market before committing resources. That discipline is exactly what FP Collectiv teaches. If you want to build it properly, start with B2B Marketing Fundamentals.
