Product-Market Fit

Also: PMF

Definition. The state where a product satisfies strong, sustained demand in a good market — customers buy, use it repeatedly, and recommend it organically. The prerequisite for scalable GTM: trying to scale a motion before PMF amplifies waste rather than growth.

In practice

Marc Andreessen's framing: a good market with a product that can satisfy it. Often pressure-tested with the Sean Ellis survey (% who'd be 'very disappointed' if the product vanished; ~40%+ is the rule of thumb).
