What customer success tool manages renewals and expansion revenue?

A common **customer success tool** for managing **renewals** and **expansion revenue** is **Gainsight**; it’s cited as a platform that supports customer health scoring and renewal-focused workflows, and it is specifically mentioned among tools used to drive retention and growth through renewals.[5]

Other tools in the same category include **Vitally**, **ChurnZero**, **Totango**, and **Catalyst**.[5] Renewtrak is also highlighted, but it is described as being **purpose-built for renewals** rather than a broader customer success platform.[5]

If you want, I can also compare these tools by **renewals automation**, **expansion tracking**, and **best fit by company size**.
