Builds foundation models for software engineering and the agents that run them, for enterprises and government.

## Overview

Poolside is an AI company that trains its own foundation models for software engineering and sells agents that run on them. Its open-weight Laguna models include S 2.1 and the smaller XS 2.1, which is small enough to run on-device.

The Poolside Platform runs self-managed agents inside the customer’s own security boundary, including on-premises and air-gapped environments. Developers work through the pool CLI or the Poolside Assistant for VS Code, Visual Studio and macOS, and can add MCP servers.

Poolside sells mainly to large enterprises and government on a subscription basis without per-token fees, with free developer previews also available. Its models are also offered on Amazon Bedrock, OpenRouter and Vercel AI Gateway.

**Who it is for:** Large enterprises and government organizations.
