poolside

Overview

Poolside is a U.S. artificial-intelligence company founded in 2023 that develops foundation models, APIs, and coding assistants for software engineering. Its products focus on code generation, completion, software design, review, and longer-running development tasks rather than general consumer chat. The company is positioned toward enterprise and public-sector customers, with emphasis on security, privacy, and deployment within customer-controlled environments.

History

Poolside was founded in 2023 by Jason Warner, former chief technology officer of GitHub, and Eiso Kant, a software entrepreneur. The company raised early funding in 2023, including reported seed and Series A financing, before raising $500 million in October 2024 at a reported $3 billion valuation. It developed foundation models specialized for software engineering, including Malibu for reasoning and Point for code completion, alongside coding-assistant products and APIs. Poolside has maintained operations in the United States and France and is reported to remain independent despite strategic investment activity.

Manufacturing

Poolside does not manufacture physical products. It develops and trains software models in-house using its Model Factory and GPU infrastructure, while deploying software and models within customer-controlled environments where required.

Notable Products

• Malibu - A foundation model positioned for deep reasoning and conversational software-development work.
• Point - A code-completion model designed to assist developers while writing software.
• Poolside Assistant - An AI coding assistant available through Poolside’s developer tools and editor extensions.
• Poolside API - An API and enterprise platform for integrating Poolside’s software-engineering models into development workflows.
• Model Factory - An internal model-training and experimentation platform supporting evaluation, reinforcement learning from code execution, synthetic data generation, and model development.

Reputation

Poolside is generally regarded by AI and developer-industry observers as a well-funded specialist focused on software-engineering models and enterprise deployment. Its perceived strengths include experienced founders, substantial financing, dedicated code-model research, and attention to customer-controlled infrastructure. Criticisms and uncertainties center on limited public information about product performance, pricing, customer adoption, and the difficulty of competing with larger general-purpose AI providers and established coding assistants.
