Logo Churn

Logo churn is the rate at which CUSTOMERS leave, counted by number ('logos') rather than by revenue — 9 of 100 customers gone is 9% logo churn, whether they were your biggest accounts or your smallest. It's the headcount complement to revenue (dollar) churn, and the gap between the two numbers is itself a diagnosis.

The relationship reads like an X-ray: when logo churn EXCEEDS revenue churn, you're losing small accounts while keeping big ones (often an SMB-onboarding or product-fit problem at the low end — survivable but a signal); when revenue churn exceeds logo churn, you're losing your BIG accounts (an emergency — few departures, outsized damage). Equal rates mean churn is size-blind. Logo churn matters for product-led and SMB businesses where volume and expansion-base breadth drive the model; revenue churn matters more where a few enterprise accounts dominate. Tracking both, by segment, is the only honest retention picture.

Logo churn matters as the base-breadth health check — the count of relationships, which seeds future expansion, word of mouth, and the law of large numbers PLG depends on. It's the right denominator for community and network effects (you need logos, not just dollars). Its trap is reading it alone: a SaaS with gorgeous net dollar retention can be hemorrhaging logos, surviving on a handful of expanding whales — a fragile position one whale's departure exposes.

*The coinage has no clear author on record; below is the best-supported reconstruction. 'Logo' as B2B slang for a customer account (from the practice of displaying customer logos on slides) gave the metric its name; the logo-versus-revenue-churn distinction standardized in 2010s SaaS finance vocabulary as subscription analytics matured.
