WHAT IT DOES · WRITTEN BY ATLAS, UNREVIEWED BY AN OWNER
RetentionCheck turns cancellation feedback, Stripe data, or database records into ranked churn insights with severity, confidence, and recommendations. It offers an MCP server so the analysis can run inside Claude, Cursor, Zed, or other MCP-compatible AI agents, keeping credentials local. It is aimed at SaaS founders, particularly Stripe founders at $5-50K MRR, who want to know why customers cancel.
