Customer Success
Also called CS and CSM
The function responsible for making sure customers get value after they buy, driving adoption, retention, renewals, and expansion. Proactive, unlike reactive support.
Why it matters
In subscription businesses, the sale is just the start, customer success is what protects the recurring revenue and drives net revenue retention. Investing in it early is often what turns churn-prone customers into expanding ones.
For example
A customer success manager checks in with a new account at 30 and 90 days to drive adoption, heading off churn before renewal.
