Before investing in top-of-funnel marketing, ensure your core growth engine works. Gamma paused all other efforts and dedicated their entire team for months to perfecting the first 30 seconds of the user experience. This focus on the 'aha moment' was the key to unlocking true organic virality.

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 a full product overhaul, Gamma bet the company on perfecting the initial 30-second user experience. By making onboarding so magical that users felt compelled to share it, they unlocked true organic, viral growth that had previously been missing.

Gamma's CEO resists the pressure to scale headcount aggressively, arguing that doubling the team size does not guarantee double the speed. He believes a smaller, more agile team can change direction faster, which is more valuable than raw speed in a rapidly evolving market.

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.

Sales are a vanity metric for product-market fit. The real test is having ~25 customers who have successfully implemented your product and achieved the specific ROI promised during the sales process. If you don't have this, you have a product problem, not a go-to-market problem.

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.
