Retain
What it is
Retain analyzes product-usage and payment signals to score customer account health, identify churn risk, and explain the reasons behind that risk. Its AI examines more than 10 behavior signals, including feature usage, onboarding, trends, quiet days, and billing. Health scores run from 0 to 100, map to risk levels, and recalculate daily from current behavior. Retain can identify a Best Retention Trigger shared by successful customers and compare retention by signup month, plan, channel, or account size. It groups customers by lifecycle stage, sends contextual churn alerts, and prepares win-back messages based on customer changes. Product events can arrive through its SDK or API or from PostHog; subscription data can come from Stripe or Polar, and alerts can go to Slack or Discord. MCP access exposes seven tools to AI clients including Claude, Cursor, Codex, Gemini, and Perplexity. Retain is for B2B SaaS companies past product-market fit with high-value customers and lean customer-success teams. There is no free plan; pricing starts at $79 a month, with a 14-day trial.
