What Poolside does
Poolside is a private foundation-model and AI-agents company focused on software engineering. The company builds open-weight “agentic coding” models and a production platform intended to run inside customers’ security boundaries—so teams can write, understand, test, refactor, and operate complex codebases without sending their code, prompts, or outputs outside their environment.
Product-wise, Poolside offers: - Models for coding workflows, including the Laguna model family and other supporting model offerings. - An IDE/desktop experience via Poolside Desktop Assistant for macOS, plus extensions for VS Code and Visual Studio. - An enterprise AI platform (“Poolside Platform”) designed for deploying and managing AI agent workflows within customer infrastructure, emphasizing governance, auditability, and telemetry. - Additional deployment surfaces described in the documentation, including a browser chat experience, a terminal/CLI agent runner, a console for administrative operations, and APIs for integration.
Technically, Poolside describes an internal “Model Factory” approach for building and iterating on foundation models, including mechanisms designed to use reinforcement learning signals derived from code execution feedback (RLCEF).
Strategically, the company appears to be pushing two parallel tracks: (1) improving frontier-class (or “frontier-class reasoning”) open-weight coding models such as Laguna S 2.1 and Laguna XS/M series, and (2) packaging deployment/operations systems so enterprises can adopt those models in environments with high security and governance requirements.
