Login frequency decline
Horizon: 45 days before churn. A 40%+ drop in authenticated sessions over a 30-day window. The most universal churn signal across SaaS verticals.
How to detect it
Compare trailing-30-day session count to the trailing-60-to-90-day baseline. If sessions/week drop below 60% of baseline for 2+ consecutive weeks, fire the signal. Threshold is industry-agnostic — works identically in HR tools, CRM, BI dashboards.
Recommended intervention playbook
Contact the account within 7 days of signal fire. Diagnose: (1) champion on leave or departed? (2) competing tool adopted? (3) use-case fit regression? (4) UI/UX friction introduced by recent release? Interventions differ per cause — do not send generic re-engagement emails without diagnosis.
