Jarmin builds AI employees companies hire to fill roles across their teams. Rather than a tool someone has to operate, a Jarmin employee is assigned a role and its responsibilities, learns the company's systems and processes, and does the work to production quality. Jarmin was founded in 2025 by Chalmers Brown, Zack Leman, and Shirsendu Halder, who previously worked on models, agents, and the infrastructure underneath them at Meta Superintelligence Labs, Apple, AWS, Lockheed Martin, and JPMorganChase. The company is based in San Francisco and is backed by Y Combinator.
