About
Poolside is an artificial intelligence company founded in 2023 by Jason Warner and Eiso Kant and headquartered in San Francisco, California, with offices in Paris, France. The company is developing a generative AI foundation model designed specifically for software engineering tasks — including code generation, completion, debugging, refactoring, and explanation. Poolside differentiates from general-purpose large language models by training its models using a reinforcement learning approach based on code execution feedback rather than solely on static text prediction, which the company argues produces models that better understand code correctness and runtime behavior rather than simply pattern-matching on syntax.
