SCIM (System for Cross-domain Identity Management) is an open standard that enables seamless user identity management across different systems and apps. By automating the process of creating, updating, and deleting user accounts in multiple places, SCIM streamlines onboarding, reduces support overhead, and enables frictionless scale. Most successful SaaS companies have tapped into this quiet growth engine to fuel product adoption, drive expansion, and increase stickiness. SCIM is not just a backend protocol but a go-to-market tool that accelerates growth and unlocks scale, especially for productivity and collaboration tools targeting fast-moving teams. By integrating SCIM early in their journey, startups and scale-ups can offer security-conscious buyers confidence that their product can scale with their org, differentiate themselves from competitors, and start growing faster. With platforms like WorkOS making SCIM implementation radically easier, there's never been a better time to build it in early and reap the benefits later.
