To get unbiased feedback, don't mention your product. Instead, ask prospects about their #1 challenge. If they organically bring up the problem your product solves, you've found a real pain point and strong market pull.

Many founders assume that identifying a customer's "pain point" signals a business opportunity. However, most people tolerate countless pain points without acting. True demand comes from an unavoidable, active project for which they are seeking a solution, not just a passive problem.

The default state for any new product is zero demand. Instead of trying to create desire, your job is to find the rare, pre-existing conditions where a customer is so urgently blocked on a project that they would be irrational not to buy your solution.

The most significant mindset shift for founders is realizing they can't force a customer to have demand. Demand is an objective state in the customer's world—a project they are already trying to accomplish. This transforms sales calls from high-pressure convincing into low-pressure discovery, liberating the founder from feeling responsible for the outcome.

The clearest signal of product-market fit isn't just revenue growth; it's the shift from proactive, outbound sales to reactive, inbound interest. When potential customers start seeking you out, filling forms, and requesting quotes based on reputation and word-of-mouth, you've crossed the chasm from pushing a product to pulling a market.

Most problems customers describe are "pain points" they won't act on. You can't distinguish these from real, actionable demand ("pull") through interviews alone. The only true test is presenting a viable solution and attempting to sell it. Their reaction—whether they try to pull it from you—is the only reliable signal.

Founders mistakenly believe they can manufacture demand through better positioning or features. This is the "supply trap." True demand must exist independently before your product arrives. Your role is to find customers who are already "spring-loaded" (coping or blocked) and unleash their existing pull.

The "Pull Framework" defines demand not by pain, but by observable action. It requires a customer to have an active, unavoidable project, to have already explored existing options, and to find those options insufficient. This is the signal for a product they will eagerly "pull" from your hands, even if it's imperfect.

During validation calls for Merge, prospective customers expressed extreme annoyance with the status quo but were skeptical the founders could technically solve it. This combination was the ultimate signal: the pain was immense, and a successful solution would be highly defensible and valuable.
