Architectural Logic & Strategy

Customer churn is rarely a surprise on renewal day—it begins weeks or months earlier when user activity declines, key champions leave, or support tickets escalate without resolution.

This retention stack bridges the gap between raw product telemetry and high-touch account management. Vitally unifies account health scores, while Fathom records customer quarterly business reviews (QBRs) and surfaces unaddressed objections.

When user activity dips below critical thresholds, Customer.io automatically fires personalized re-engagement campaigns to users, prompting them to unlock maximum product value before churn occurs.
