WorkOS's Michael Grinich on Becoming the Enterprise Layer for AI's Biggest Companies
Founders in Arms
Lessons from burnout at Nihilus
Michael reflects on mistakes at his first startup and what he learned about hiring and CEO growth.
Michael Grinich is the co-founder and CEO of WorkOS, the enterprise authentication and identity infrastructure used by Anthropic, OpenAI, Cursor, xAI, and hundreds of fast-growing companies. Before WorkOS, Michael dropped out of MIT, worked at Dropbox, and founded Nihilus — where a painful first experience with enterprise features planted the seed for everything that came next.
In this episode, Immad Akhund and Raj Suri sit down with Michael to talk about the SaaS apocalypse thesis, how WorkOS quietly became the enterprise layer for AI's biggest companies, and what it actually takes to build for developers.
What you'll learn:
- Why the SaaS apocalypse narrative gets it completely backwards
- How WorkOS became the default enterprise-ready layer for AI-native companies
- The Stripe parallel: why developer infrastructure compounds the same way payments did
- What a failed first startup taught Michael about idea validation
- How keeping a daily idea notebook — volume, not quality — led to WorkOS
- Why second-time founders approach conviction and validation completely differently
- The do-or-die bond between developer tools and their customers
- How Michael taught himself enterprise sales after starting as a purely technical founder
- Why building for developers is the ultimate boss battle in tech
- What AI getting to Renaissance-printing-press level actually means for software
