The Economics of Free: When Zero Breaks the Pricing Curve

In this episode of Mostly Growth, Kyle Poyar, CJ Gustafson, and Ben Hillman break down the economics and psychology of “free,” explaining why the jump from free to even $0.01 fundamentally changes behavior. They unpack freemium, free trials, reverse trials, ungated products, and credit-card trials, sharing real conversion benchmarks and CFO-level tradeoffs between acquisition and revenue. The takeaway: “free” isn’t one strategy—it’s a set of levers that must match what you’re optimizing for.—SPONSORS:HockeyStack is an AI platform for modern go-to-market teams that unifies sales, marketing, and customer data into a single system of action.
