Bespoke Labs

Reinforcement learning platform for agents

Overview

Bespoke Labs builds reinforcement-learning (RL) solutions for autonomous agents. Its work centers on creating tools and workflows that let agents learn from interactions, either in simulated or real environments, to perform tasks or make decisions. The product works by providing a training loop: an environment where the agent acts, a library of RL algorithms, and a pipeline to train, evaluate, and deploy the learned policies. Users supply their task and environment, and Bespoke Labs tunes the RL setup to achieve good performance, then ships a model that can be integrated into the user’s systems. The company differentiates itself by offering customized RL solutions tailored to specific business problems and environments, rather than a one-size-fits-all product. Its goal is to help organizations scale intelligent agents that can automatically improve through experience and carry out complex tasks with minimal human intervention.

Bespoke Labs raises $40M to build AI agent training environments

Bespoke Labs has raised $40 million to build training environments for AI agents. The funding comprises a Series A round led by Wing VC and a seed round led by 8VC, with participation from Mayfield, The House Fund, and executives from Anthropic, OpenAI, and Meta. The Mountain View-based company, founded in 2024 by Mahesh Sathiamoorthy and Alex Dimakis, creates realistic corporate environments—complete with codebases, microservices, and communication tools—where AI agents can practise long-term tasks. The platform helps organisations measure and improve agent performance using techniques like its Genetic-Pareto Agent Optimizer. Bespoke Labs takes a research-first approach, contributing to Terminal-Bench and OpenThoughts, which has been downloaded over 500,000 times. The capital will fund research expansion, hiring, and infrastructure scaling.
