What ChartMogul does
ChartMogul connects to your billing system (Stripe, Recurly, Chargebee, Braintree, ProfitWell, manual import) and gives you dashboards for MRR, ARR, churn rate, LTV, cohort retention curves, and customer segmentation. It answers "what is happening to the numbers?" with charts and segments. The free tier under $10K MRR is generous; paid plans run $129-$999+/mo at growth scale.
What RetentionCheck does differently
RetentionCheck answers the question ChartMogul does not: "why are customers actually canceling?" You paste qualitative feedback (exit surveys, Stripe cancellation reasons, support tickets, Trustpilot reviews) and get severity-ranked churn drivers with verbatim quotes and one priority action. It works independently of your billing system, so the input source can be anything text-based.
When to use ChartMogul
Use ChartMogul when you need quantitative subscription analytics: real-time MRR tracking, cohort retention curves, expansion vs contraction breakdown, customer segmentation by plan or geography, revenue forecasting. It is the dashboard for your subscription business metrics. The free tier under $10K MRR makes it the default cheap option for early-stage SaaS.
When to use RetentionCheck
Use RetentionCheck when ChartMogul tells you churn spiked 2% last month and you need to know why. RetentionCheck takes the cancellation feedback that produced that spike and returns the underlying drivers: 35% pricing-value mismatch after a price increase, 22% specific feature gap, 18% support response time. The trend chart and the driver list answer different questions on the same data.
The verdict
Complementary tools at different layers of the same problem. ChartMogul tells you the number is moving; RetentionCheck tells you what is moving it. Most founders running ChartMogul also need a way to read the qualitative feedback that produced the numbers, and most founders running RetentionCheck eventually want a dashboard view of the trend. The combination is common past $20K MRR. The free tier of each makes it cheap to try both.
