Phaidra

Market position

Phaidra was named one of ten ecosystem specialists for AI factory operations by NVIDIA in September 2025 and is a contributor to NVIDIA's Omniverse DSX and Vera Rubin DSX AI factory reference designs. It was recognized by TIME as one of America's Top GreenTech Companies of 2026. Its market is defined against traditional building management systems that adapt poorly to variable AI workloads; other companies cited in the space include BrainBox AI.

Phaidra pairs general-purpose reinforcement learning with deep domain expertise in mission-critical cooling and industrial controls, targeting coordinated control across power, cooling and workload systems as one integrated unit of compute rather than isolated subsystems. Its founding team's track record includes Google data center cooling optimization and the AlphaGo project at DeepMind.

Technology

The platform combines reinforcement learning with domain expertise in mission-critical cooling, data centers and industrial controls to create self-learning, autonomous control systems. Agents apply feed-forward, predictive control on production NVIDIA Grace Blackwell platforms and across liquid cooling loops and chiller plants; Phaidra also emphasizes data readiness, describing classes of data (including contextual "class 3" and simulated "class 4" data) required to safely operationalize predictive AI control. A separate LLM-based product, Phaidra Prism, targets diagnostic and troubleshooting workflows for operators.

Go-to-market

Phaidra goes to market largely through partnerships and ecosystem integrations — with NVIDIA (Omniverse DSX and Vera Rubin DSX blueprints), CoreWeave, Applied Digital, Salute, InfraPartners, ST Telemedia Global Data Centres and Khazna Data Centers/Agility — supplemented by product launches at industry events such as NVIDIA GTC, conference speaking, white papers, blog content and inbound demo requests.

Hyperscale and colocation data center operators, AI factory and neocloud providers, prefabricated data center developers, and operators of other mission-critical industrial facilities such as pharmaceutical production sites and district cooling systems.

Geography

Headquartered in Seattle, United States, with deployments and collaborations extending to Singapore (ST Telemedia Global Data Centres) and the United Arab Emirates (pilot with the UAE Ministry of Energy and Infrastructure, Khazna Data Centers and Agility); the Series B is intended in part to fund expansion to additional global operators.

History

Founded in 2019 by ex-DeepMind and Google data center engineers, Phaidra published research on autonomous AI control of mission-critical cooling at Merck in 2024 and announced a collaboration with ST Telemedia Global Data Centres for Singapore data centers in August 2024. Index Ventures led an additional funding round in July 2024 that brought reported total funding to $60M. In March 2025 NVIDIA announced a partnership to integrate Phaidra's reinforcement-learning agents into its Omniverse blueprint for AI factory design, and in September 2025 named Phaidra one of ten ecosystem specialists for AI factory operations. A Series B of more than $50 million led by Collaborative Fund was announced on 1 October 2025. In October 2025 Phaidra joined NVIDIA's Omniverse DSX blueprint for gigawatt-scale AI factories, and in 2026 announced a UAE government pilot, the Phaidra Prism platform launch at GTC26, Max-Q AI factory work with CoreWeave and Applied Digital, and partnerships with Salute and InfraPartners.

Risks & controversies

Efficiency figures such as 20-30% or 40% energy savings and the ~80% reduction in thermal spikes are reported by the company or its partners rather than independently verified. Reported funding totals differ across sources, and no post-money valuation has been disclosed for the Series B.
