ChurnAlert gives indie founders a simple churn early warning system. Connect Stripe in 30 seconds and it automatically scores every customer 0 to 100 based on 8 risk signals: inactivity, payment failures, cancellation intent, usage dropoff, and more. Every Monday morning you get a ranked digest in your inbox showing who's at risk and how much MRR is on the line, so you can reach out before they cancel. Built by a solo dev who was tired of finding out about churn after it was already too late.
