A strong startup customer success manager job description says which part of the customer lifecycle the CSM owns, whether they carry a renewal or expansion number, and how many accounts they will manage. Those three decisions change the profile you should hire, from a technical onboarding specialist to a commercial account manager, so make them before you write anything else.

What we offer
Mark in the JD which of these four stages the CSM owns. Many first CSM hires go wrong because the founder wanted a commercial renewal owner and hired a friendly onboarding specialist, or the other way round.
| Seed | Series A | Series B | |
|---|---|---|---|
| Book size | Every customer | A segment, by size or region | A defined book by tier |
| Commercial ownership | Often none, founder renews | Renewals, sometimes expansion | Renewal and expansion targets |
| Support | CSM answers tickets too | Shared with a support person | Separate support team |
| What to stress in the JD | Building onboarding, product feedback | Health scores, renewals, playbooks | Tiered coverage, targets, working with sales |
| Outcome | What good looks like at 12 months | How you'll test it in interviews |
|---|---|---|
| Retention of their book | Renewals at or above your target, churn explained | Ask for their last book: accounts, renewals, losses |
| Time to first value | New customers reach the milestone within your target | Ask how they onboarded a complex customer |
| Early warning on risk | At-risk accounts flagged well before renewal | Give them usage data and ask who is at risk |
| Expansion, if owned | Expansion revenue at target | Ask how they spotted and handed over expansion |
| Product feedback | A monthly, ranked list product acts on | Ask what product change they pushed for |
| Period | Focus | By the end they should have |
|---|---|---|
| Days 1 to 30 | Know every account | Met or called every customer in their book, read past tickets, listed the top risks |
| Days 31 to 60 | Onboarding and health | A written onboarding checklist, a first health score, a renewal calendar |
| Days 61 to 90 | Renew and report | First renewals closed, first monthly product feedback report, one at-risk account turned around |
