Activation
Also known as: activation event · aha moment
The event that marks a new user reaching "first value" — the behaviour that predicts they'll stick around, used as the exit-criterion for onboarding programs and the primary KPI for lifecycle teams working top-of-funnel.
Activation is the specific event that predicts long-term retention. For a product-led SaaS, activation is often "completed first integration" or "invited a teammate." For a marketplace, it's "completed first transaction." For a subscription product, it's usually a combination of depth of use + cadence (3 sessions in 7 days, used feature X, imported data). Finding the right activation event is a data job: look at what distinguishes users who retained past day-30 from users who churned; whatever behaviour cleanly separates the two, within the first 7-14 days, is your activation. The number matters less than the consistency — lifecycle programs should be built against one activation event, not five. Onboarding programs exist to drive users to activation; winback programs exist to reactivate users who lapsed after activation.

The first 72 hours decide who activates
Activation isn't a seven-day project. It's a 72-hour race most teams lose without noticing. Why the window is that short, what to watch inside it, and how to intervene while users are still reachable.
Onboarding flows: signup to activated
Most onboarding programs fail in the same three ways — no activation metric, no awareness of what the user just did in-product, and a sequence that won't stop once the user has clearly activated. Fix those three and the program starts moving signups to activated users in numbers you can actually defend.
