Activation Design Onboarding

Activation is the moment a user gets value from your product. For Slack, it's sending a message. For Stripe, it's processing a payment. For Notion, it's writing a note. Activation is not signup; it's the first experience of core functionality. Most products have 70–90% signup-to-first-action drop-off. Of those who act, 50–70% don't return. The gap between signup and activation is your biggest churn lever.
