Overview
Poolside Infrastructure Company builds large language models for software development, offering a foundation model, API, and an IDE-integrated AI assistant to help with code generation, testing, and refactoring. The models are trained in-house with a full-stack approach, and can be fine-tuned on a client’s codebase with on-premises deployment to protect data. A differentiator is RLCEF (Reinforcement Learning from Code Execution Feedback), which uses synthetic data generated by the model to improve performance and data efficiency. Poolside targets developers to large enterprises and regulated sectors, partners with AWS for deployment on platforms like Amazon Bedrock, and aims to make AI-assisted software development more capable and secure while safeguarding sensitive data.

What believers are saying
- AWS updated October 3, 2026 to make Poolside first managed models on Bedrock.
- August 2026 Nvidia added $1 billion equity and 109 employee offers.
- July 2026 Laguna S 2.1 open-weight release broadened adoption among developers and teams.
What critics are saying
- April 2026 CoreWeave killed Project Horizon, leaving Poolside without its 2-gigawatt campus.
- August 2026 Nvidia's $6 billion license and hires expose dependence on one buyer.
- If AWS or Nvidia pivots, Poolside loses distribution, compute, and financing before 2027.
What makes Poolside Infrastructure Company unique
- Poolside's September 2026 Bedrock launch embeds Malibu and Point inside developer IDEs.
- April 2026 Laguna models and RLCEF create proprietary code-training and execution-feedback loops.
- Dell on-prem deployments target defense, finance, and healthcare with air-gapped installations.
