Best fit for
If you run any of these, ChurnStop is a good match out of the box:
- Subscription boxes- Box stores get hit hardest on schedule conflicts and variety fatigue, not price. ChurnStop routes "not using" to skip-renewal and "missing a feature" to product-swap so you stop discounting churn you did not cause.
- Membership sites- Member churn is driven by life events and attention budget, not price. Pause converts 2–3x better than discount for memberships because it matches how members actually think about their commitment.
- Replenishment commerce- Customers who subscribe to consumables cancel on timing, not intent. A skip-renewal offer converts 40%+ of "not using" cancellations. The product is fine. The cadence is wrong.
