Overview
The Hook Model introduces a framework for creating habit-forming products. It consists of four key components: Trigger, Action, Variable Reward, and Investment, which together drive user engagement. The founder lens is simple: keep the parts that improve judgment, simplify decisions, and make the next move easier to explain.
