Bespoke Labs builds realistic environments that simulate company infrastructure—codebases, microservices, logs, tickets, email, and Slack—to train long-horizon AI agents. The company emphasizes a research-first approach, staffed by research scientists and engineers rather than contractor-driven teams. Bespoke Labs contributes to open benchmarks and datasets such as Terminal-Bench and OpenThoughts and develops techniques like the Genetic‑Pareto Agent Optimizer (GEPA) for automated prompt and policy search. Its customers use the platform to train, evaluate, and optimize agents, and the company focuses on environment curation, synthetic environment generation, and snapshotting real-world infrastructure. Founded in 2024 by Mahesh Sathiamoorthy and Alex Dimakis, Bespoke Labs is based in Mountain View and recently raised $40 million to scale research, infrastructure, and business efforts.
