The client’s problem
The team found out a client was unhappy only after they cancelled, and checking client health took hours every week.
What I built
An AI-powered monitoring engine that scans every client in Google Sheets daily, scores churn risk 0 to 100 using GPT-4o-mini against real behavioral signals (logins, invoice status, renewal proximity), and fires instant Slack alerts the moment a client hits at-risk, plus a full AI-written weekly retention report every Monday.
The outcome
Enterprise clients are scored daily with no filters. Pro and Basic clients are only sent to AI when real warning signals exist. The team always knows who needs a call, before the cancellation request arrives.
