Poolside AI is a frontier AI lab building foundation models and enterprise AI agents purpose-built for software engineering. Founded by Jason Warner (former GitHub CTO) and Eiso Kant, the company has raised over $1.6 billion with a $12 billion valuation backed by Nvidia, Bain Capital, and others. Poolside's platform is powered by two proprietary models: Malibu, which excels at complex software engineering tasks including code generation, test writing, refactoring, and documentation with over 1 million token context; and Point, a low-latency code completion model with advanced context awareness that accurately predicts developer needs. Both models are trained using Reinforcement Learning from Code Execution Feedback (RLCEF), a novel approach that improves performance by learning from actual code execution results. Unlike typical SaaS coding tools, Poolside deploys directly within customer infrastructure — on-premises, VPC, or air-gapped environments — ensuring complete data privacy and control. The platform integrates across IDEs (VS Code, IntelliJ), terminals, browsers, and APIs, with models that fine-tune on each organization's codebase, practices, and documentation. Poolside also offers multi-agent systems capable of planning, tool usage, and execution in sandboxed environments with end-to-end tracing and policy governance. Available on AWS Bedrock for cloud deployment, Poolside is designed for enterprise, government, and defense customers who need the most capable AI coding assistant with uncompromising security.
