Activation
The point at which a new user first experiences the core value of a product — the 'aha moment' that predicts whether they'll stick around.
Activation is the moment a new user gets the point — sends the first message, sees the first report, completes the first transaction. Teams define it as a concrete milestone ("invited a teammate within 24 hours") because users who reach it retain far better than those who don't.
It is the hinge between acquisition and retention: traffic is wasted if people never activate. That makes onboarding design — removing every obstacle between signup and first value — one of the highest-leverage surfaces in the whole product.
