Tony Holdstock-Brown
Tony Holdstock-Brown is the co-founder and CEO of Inngest, a San Francisco developer platform that gives engineers a durable, observable execution layer for background jobs, workflows, and AI agents. A self-described tinkerer since age 10 and former Docker engineer, he started Inngest in 2021 with CTO Dan Farrelly after the two met in a New York co-working space. The company has raised roughly $31.6M, including a $21M Series A led by Altimeter in 2025, on the thesis that in an AI era the real moat is how fast a team can iterate.
