Poolside AI

AI trained on software execution for superhuman code generation

Emerging & FrontierPaid

Poolside AI is a generative AI company building foundation models specifically optimized for software engineering through reinforcement learning from code execution. Unlike models trained primarily on static code text, Poolside's training loop uses actual program execution outcomes — tests passing, builds succeeding, runtime behavior — as reward signals, producing models that better understand the semantics of code rather than just its syntax. The company is building both a developer-facing coding assistant and an API for embedding high-fidelity software generation in other products.
