The single most reliable churn predictor is a drop in the action that defines value for that customer. Yet most teams only spot it at the QBR — long after the account quietly disengaged.

The alert framework

  • Define the core action per segment. It differs by use case. Pick the one action that, when it stops, value stops.
  • Baseline each account to itself. A 40% drop matters relative to that account's normal, not an absolute threshold.
  • Alert on sustained dips, not noise. A two-week sustained decline triggers; a single quiet day doesn't.
  • Route to an owner with a play. An alert nobody acts on is worse than none. Pair every alert with a defined next step.

Bottom line: instrument the one action that equals value, baseline it per account, and route sustained dips to a human with a play.
