TL;DR
ChartMogul is a mature, multi-source subscription analytics platform with strong data-cleaning, segmentation and reporting — ideal if you bill across several systems and want a flexible data layer. RetentionLens is Stripe-first and lighter to adopt, and it adds predictive churn (survival analysis / Cox model) and customer health scoring plus a free tier, so it suits teams that want forward-looking churn signals without a data project.
ChartMogul is a powerful subscription-analytics data platform. Its strengths are multi-source ingestion (Stripe and many billing systems), robust data cleaning, and deep segmentation. For teams that bill across several systems and want a flexible analytics layer, it is excellent.
RetentionLens is deliberately Stripe-first: one solid source, fast time-to-value, and predictive churn modelling on top. Rather than competing on integration breadth, it competes on depth of insight — telling you who is likely to churn and how healthy each account is.

RetentionLens is Stripe-first by design — one solid source, fast time-to-value — with optional enrichment from CRM and support tools. If you must unify several billing systems on day one, ChartMogul’s multi-source model is the better fit.
RetentionLens models which customers are likely to churn next using survival analysis (a Cox proportional-hazards model) and surfaces customer health scores. ChartMogul focuses on descriptive analytics and segmentation rather than predictive churn scoring.
Both offer a way to start without paying: RetentionLens has a free Starter tier, and ChartMogul has historically offered a free tier for early-stage companies. Verify current limits on each site.
