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.
DBOS, Inc.
DBOS, Inc. is a San Francisco- and Cambridge-based developer infrastructure company commercializing durable execution technology born from a joint MIT-Stanford research project led by Postgres creator Michael Stonebraker and Apache Spark creator Matei Zaharia. Its flagship open-source library, DBOS Transact, adds crash-proof workflow orchestration and built-in observability to ordinary Python and TypeScript programs by persisting application state in Postgres, so software resumes exactly where it left off after a failure - without a separate workflow server. The company pairs the library with DBOS Conductor and DBOS Cloud for managing and hosting reliable backends, AI agents, and long-running workflows.
