After setting a modest goal of signing 10-20 hotels at their first major conference, Canary Technologies signed over 200 in just eight hours. This massive, unexpected pull from the market served as the definitive, visceral signal that they had achieved strong product-market fit.

Founders often try to convince themselves they have PMF. The actual moment of achieving it feels like a sudden, unmistakable change—a switch, not a spectrum—making it clear that all previous feelings were just wishful thinking.
Product-market fit isn't a sudden switch but a palpable shift in momentum. As a founder, you feel the change from pushing against the current (hard selling with little traction) to suddenly being pulled by it (easier sales, inbound interest). This directional change in velocity is the clearest signal that you're onto something.
This visceral analogy reframes product-market fit as an uncontrollable, overwhelming demand from the market. It's not just positive metrics; it's a state of being swarmed by customers. If you don't feel this intense 'market pull,' you haven't truly achieved it and must keep iterating.
Product-market fit isn't just growth; it's an extreme market pull where customers buy your product despite its imperfections. The ultimate signal is when deals close quickly and repeatedly, with users happily ignoring missing features because the core value proposition is so urgent and compelling.
You've achieved product-market fit when the market pulls you forward, characterized by growth driven entirely by organic referrals. If your customers are so passionate that they do the selling for you, you've moved beyond just a good idea.
Canary's founders achieved an impressive 50-75% demo-to-close rate in the early days. While this rate decreases as a sales team scales, such a high initial conversion is a powerful leading indicator of product-market fit, proving that qualified buyers want the product once they see it.
In the early days, Canary's pitch received mixed reactions. However, the strong, visceral "I need this now" response from a few customers was a more valuable signal of product-market fit than getting a polite "that's cool" from everyone. This validates the "10 true fans" principle in B2B.
Founders without product-market fit constantly optimize small things, believing better execution is the key. In contrast, with PMF, solid execution yields disproportionate results. Sales calls close without "Jedi mind tricks" because customers want the product.
Product-market fit is confirmed through repetition. For Decagon, it was when the fifth and sixth customers independently described the same core problem, cited the same failed competitors, and expressed immediate willingness to buy, proving a repeatable market need.
The unambiguous signal of Product-Market Fit (PMF) isn't a magic number in your analytics. It's when customer pull becomes so strong that it breaks your supply chain, logistics, and team capacity, forcing uncontrollable growth even without marketing spend.
