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.

Building customer success from scratch: A framework for B2B SaaS Customer Success Collective · article Written for exactly your situation: no CS hire, the founder is customer success. It rejects expensive tooling and builds the whole function on a CRM, a Google Sheet, and basic automation, so a tiny Indian team can run it tonight. Concretely it tells you to ask the customer point blank what success looks like for the company and for each stakeholder, track activation and usage (not ticket volume) as your health signal, and run monthly or quarterly reviews decoupled from renewal pressure so check-ins are not read as a sales push.
