The one-person CSM at a 60-person startup.
A one-person CSM at a 60-person Series-B SaaS startup ran 92 accounts in a Google Sheet with health tracked as a vibe check. Renewal surprises hit every quarter. Strkr onboarding ran a nine-business-day migration (shorter than default because there was no legacy CRM). The health score, renewal triage, and QBR draft landed on day one. The CSM reclaimed about four hours a week and net revenue retention climbed four points over the next six months.
