Poolside

Poolside is a frontier AI lab building foundation models, agents, and enterprise systems for software engineering — with the explicit bet that the fastest path to AGI runs through code. Its product stack includes proprietary models (Malibu, Point), single- and multi-agent orchestration, IDE and terminal surfaces, and connectors to private code, knowledge, and data; deployments run on-prem, in customer VPCs, or in air-gapped/defense environments. The 'Forward Deployed Research Engineer' model embeds Poolside staff inside enterprise teams to co-own outcomes. Founded in 2023, the company raised a $500M Series B in October 2024 at a ~$3B valuation (Bain Capital Ventures, Nvidia, DST, Citi, Felicis, Redpoint) and is reportedly raising another $2B at a $12B valuation in 2025.
