WorkOS provides an API platform that enables developers to quickly integrate crucial enterprise features into their applications. The company offers a suite of developer tools and services for user management, single sign-on (SSO) capabilities like SAML, directory synchronization via SCIM, and audit logging. This modern infrastructure simplifies the complexities of making software applications compliant and interoperable with enterprise IT systems, allowing product teams to focus on their core offerings while meeting demanding corporate requirements.
Michael Grinich founded WorkOS in 2019. His insight stemmed from observing the significant barriers faced by startups and growth-stage companies attempting to sell into larger organizations, which often require extensive security, compliance, and integration features. Grinich aimed to abstract away these complex enterprise-grade requirements, providing a streamlined solution that allows developers to add essential functionalities without extensive in-house development.
The platform serves developers at companies building applications that need to cater to enterprise customers. WorkOS aims to be the foundational layer that bridges the gap between consumer-grade developer experiences and the robust demands of enterprise IT. Its long-term vision is to empower any developer to build enterprise-ready applications efficiently, accelerating the adoption of innovative software within large organizations and fostering a more integrated ecosystem.
Key people at WorkOS.
WorkOS is a developer-focused API platform that provides enterprise-ready tools for identity and access management (IAM), enabling SaaS companies to quickly integrate features like Single Sign-On (SSO), Directory Sync (SCIM), User Management, Audit Logs, and Multi-Factor Authentication (MFA).[1][2][3][4][5] It serves high-growth SaaS developers and teams at companies such as Vercel, Webflow, Netlify, Perplexity, and Indeed, solving the "enterprise chasm" where startups struggle to meet complex IT security and compliance requirements for large customers, often taking months of engineering effort.[1][3][4][5] This allows them to expand from self-serve models to wall-to-wall enterprise adoption, with strong growth evidenced by a team of 80+ employees since its 2019 founding and adoption by over a dozen notable tech firms.[3][6]
WorkOS was founded in 2019 by Michael Grinich in San Francisco, California, after he recognized that SaaS companies needed to satisfy stringent enterprise IT standards—like SSO and SCIM—to achieve sustainable growth, a process that previously demanded massive engineering investment.[1][2][3][4][6] Grinich, a builder at heart, launched the company to bridge this gap with modern APIs, starting with core IAM tools and evolving into a full suite including Admin Portals for self-service onboarding.[4][5] Early traction came from developers praising features like customizable SSO UIs and seamless integrations, which turned weeks of work into minutes, fueling rapid adoption among startups eyeing enterprise markets.[1][4]
WorkOS stands out in the crowded IAM space through developer-centric design and comprehensive coverage:
WorkOS rides the enterprise-readiness wave in SaaS, where startups must "cross the chasm" from SMB self-serve to Fortune 500 contracts amid rising cybersecurity demands and compliance like SOC 2.[1][4] Timing is ideal as B2B SaaS matures—market forces like remote work, zero-trust security, and AI-driven apps amplify IAM needs, with enterprises rejecting non-compliant tools.[2][7] By influencing the ecosystem, WorkOS empowers hundreds of devs to unlock billion-dollar markets, reducing barriers for innovators like Perplexity and Vercel while challenging incumbents with modern, affordable alternatives to in-house builds or legacy providers.[3][5]
WorkOS is poised to dominate as the go-to IAM layer for next-gen SaaS, expanding into areas like fine-grained authorization (Radar) and deeper B2B auth amid AI and multi-tenant app booms.[5][7] Trends like unified APIs and self-service enterprise tools will accelerate its growth, potentially pressuring competitors through network effects from its customer base. Its influence may evolve into a full auth/user identity platform, solidifying startups' paths to enterprise scale and proving the formula for sustainable expansion that Grinich envisioned.[1][4]
