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.
