Poolside
Poolside builds highly capable AI foundation models and agentic systems for software engineering, enabling secure, autonomous code development for enterprises.
Poolside is a frontier AI lab that develops specialized foundation models and agentic systems for software engineering. These models are trained from scratch on high-quality software data using reinforcement learning, enabling long-horizon reasoning and autonomous agent behavior. The platform offers production-grade single and multi-agent systems with enterprise-first design for secure, on-premise, VPC, or workstation deployment, ensuring data privacy and auditability.
Despite massive $626M funding, Poolside faces significant challenges with the collapsed CoreWeave partnership and fundraising struggles in 2026. While their open-source Laguna XS.2 model shows technical merit, the niche position and operational difficulties prevent higher scoring.
