How would you design a feature to reduce churn in a subscription app?

Model answerChurn is a symptom, not a problem. I'd segment churned users by behavior before they left — did they stop engaging two weeks earlier? Did they never complete setup? Each segment needs a different intervention. For disengaged users: a re-engagement campaign with personalized value reminders. For setup-incomplete users: an offer to complete onboarding with support. I'd build a churn prediction model and intervene before the cancel button is even considered.
