Poolside is a frontier research lab founded in 2023, building foundation models and autonomous agents for enterprise software development through reinforcement learning from code execution feedback. The company operates millions of orchestrated coding environments seeded from open-source repositories across Python, Rust, Java, and Go, using actual code execution as the training signal rather than relying solely on language model scaling. This approach treats code execution environments as a safe playground for models to learn from experience, with the explicit constraint that feedback derives from whether code runs correctly.
The technical infrastructure spans the full stack from foundation model development in PyTorch and CUDA to enterprise deployment systems built on Kubernetes, Terraform, and AWS. The company's thesis centers on reinforcement learning as the primary scaling axis beyond traditional language model approaches, with a stated focus on high-consequence software for high-consequence applications. Co-founded by Jason Warner and Eiso Kant, Poolside is headquartered in France and positions software engineering as the fastest path toward artificial general intelligence through its experience-based learning paradigm.
