Spec score 7.7 #6 of 21 in Proactive Customer Retention Software

What it is

Retain analyzes product usage and payment signals to score customer health, identify churn risk, and explain what is driving that risk. Its AI examines more than 10 behavior signals, including feature use, onboarding, trends, quiet days, and billing. Scores run from 0 to 100, correspond to risk levels, and are recalculated daily from current behavior. Teams can compare retention by signup month, plan, channel, or account size, and identify a Best Retention Trigger shared by successful customers. Retain groups accounts by lifecycle stage, sends contextual risk alerts, and prepares win-back messages based on customer changes. Product events can arrive through its SDK or API or be forwarded from PostHog; subscription information can come from Stripe or Polar. Alerts can be configured for Slack or Discord. It also exposes seven MCP tools to AI clients including Claude, Cursor, Codex, Gemini, and Perplexity: five read data and two change alert state. Retain is aimed at B2B SaaS companies past product-market fit with high-value customers and lean customer-success or account-management teams. There is no free plan; a 14-day trial is available. Monthly plans start at $79 a month for up to 150 active accounts.
