Founders must consider their sales motion (e.g., PLG vs. enterprise sales-led) when designing the product. A product built for one motion won't sell effectively in another, potentially forcing a costly redesign. This concept extends "product-market fit" to "product-market-sales fit."

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.

Instead of vanity usage metrics, Wiz focuses on a core customer outcome: helping customers resolve all critical risks. They gamified this by creating the 'Zero Criticals Club.' This metric proves the product is driving real organizational change, a key indicator of value and stickiness that is hard to replace.

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.

Unlike traditional software where PMF is a stable milestone, in the rapidly evolving AI space, it's a "treadmill." Customer expectations and technological capabilities shift weekly, forcing even nine-figure revenue companies to constantly re-validate and recapture their market fit to survive.

Winning accolades like Product of the Day/Week/Month provides an initial user spike but doesn't guarantee product-market fit. True PMF is indicated by sustained, accelerating organic word-of-mouth growth, not a launch-driven bump that later flattens out.
