Everyone tracks signups because signups feel like progress. But signups lie. The number that actually predicts whether someone stays is activation: the single action that turns a curious visitor into a user who got value. For us it was creating a second project. Not the first, the second. One project is a test. Two is a habit forming. We found that users who hit two projects in their first week churned at four percent. Users who did not churned at thirty one. Same product, same price, wildly different outcome. So we redesigned onboarding around one job: get people to project two fast. Templates, sample data, a nudge on day three. Activation climbed nineteen points and churn followed it down. Stop celebrating signups. Find your project two and obsess over it.
