What does a CSM do?
A customer success manager owns accounts after the sale: onboarding to first value, driving adoption, running business reviews, catching churn risk early, and setting up renewals and expansion. The role converts a signed contract into retained, growing revenue.
How many accounts should a CSM manage?
The common sizing rule is $1–2M of ARR per CSM — fewer, deeper relationships in enterprise; more, tech-touch accounts in SMB. Compensation is often tied to the NRR of the book.
