Activation Rate
The percentage of new users who reach a key first-value moment (“aha moment”).
Activation measures how many signups complete the action that delivers core value (e.g. inviting a teammate, sending a first message). Strong activation predicts retention and is a leading indicator of product-market fit.
Examples
60% of signups activate within their first session. — Onboarding tweaks lift activation sharply.
