The Kirn Difference

The tools that report on churn tell you what already happened. The tools that predict it assume a customer success team and a product analytics pipeline. There is no predictive tool built for a small subscription business running on Stripe alone.

Reporting tools
Baremetrics, ChartMogul

Connect to Stripe and show MRR, churn rate, and cohort retention. Useful, but backward-looking — they tell you who already cancelled, not who is about to.

Enterprise platforms
Gainsight, ChurnZero, UserMotion

Predict churn accurately but require product usage data (login events, feature tracking), a dedicated customer success team, and budgets starting at $400/mo.

Kirn
Predictive · Billing data only · $47/mo

Scores every subscription for churn risk using billing signals alone. No CS team, no instrumentation layer. A weekly digest with who to reach out to and why.
