Poolside
Poolside is a secure, full-stack AI platform for software engineering, providing foundation models and agentic systems to automate and improve coding processes.
Poolside is an AI platform that provides foundation models and agentic systems specifically for software engineering. It helps teams write, understand, test, refactor, and operate complex codebases in production, emphasizing security and privacy by deploying within customer infrastructure. The platform offers capabilities like code generation, explanation, testing, and multi-step engineering task automation through agents, with its models learning through reinforcement learning from code execution feedback.
Despite massive $626M funding, Poolside's core partnership with CoreWeave collapsed in early 2026 and the company is struggling with fundraising and deployment. While they have open-source models, the fundamental business challenges and niche position significantly limit their current impact.
