What Phaidra does
Phaidra is a Seattle-based, venture-backed AI company founded in 2019 that develops reinforcement learning agents for autonomous control of mission-critical data center and AI factory infrastructure, specifically thermal, power, and workload management systems. The company was founded by former Google DeepMind engineers Jim Gao (CEO), Veda Panneershelvam (CTO), and Katie Hoffman (President/COO), the team responsible for the well-documented AI cooling optimization that delivered roughly 30–40% energy efficiency improvements at Google's data centers. Phaidra's platform architecture is split into two core products: Phaidra Prism, an LLM-based AI assistant purpose-built for data center operations technicians; and Phaidra Factory, a suite of specialized RL agents (including liquid cooling, CDU control, and power allocation agents) that perform feed-forward control using real-time rack power as a leading indicator, achieving response times under 10 seconds versus 3–5 minutes for traditional PID controllers and reducing thermal overshoot by 75–80% in validated NVIDIA GB200/NVL72 environments. The company serves AI factory operators, hyperscale data center operators, and colocation providers, with named engagements spanning CoreWeave, Applied Digital, ST Telemedia Global Data Centres, Khazna Data Centers, and Merck, plus a UAE Ministry of Energy pilot.\n\nPhaidra operates a subscription-based enterprise software model with custom quote-based pricing tied to facility size and deployment scope, sold primarily through direct enterprise field sales augmented by channel partnerships within the NVIDIA DSX ecosystem. The company is integrated into NVIDIA's Vera Rubin DSX AI Factory reference design and Omniverse DSX Blueprint as one of ten ecosystem specialists for AI factory operations, and has been co-developed with NVIDIA's Mission Control Domain Power Service via the NVGrid API. The business is 100% remote with a distributed workforce across North America, Europe, and India, and has raised over $60.5M in disclosed funding across pre-seed, seed, Series A, and Series B rounds, with the most recent $50M+ Series B led by Collaborative Fund in October 2025 and including strategic investment from NVIDIA and Sony Innovation Fund.

Phaidra product offering
Product offeringCore offering
Phaidra sells an AI control software platform — consisting of Phaidra Prism (an LLM for data center operations) and Phaidra Factory (specialized reinforcement learning AI agents) — that autonomously monitors and optimizes power, cooling, and workload management systems in AI factories and large-scale data centers. The platform integrates with NVIDIA infrastructure and BMS/SCADA systems to predict and prevent thermal spikes, reduce energy use, and maximize tokens per watt.
Product overview
Phaidra offers a dual-product platform architecture consisting of Phaidra Prism and Phaidra Factory. Phaidra Prism is the first LLM designed specifically for data center operations, serving as an AI assistant that helps technicians understand operating conditions, conduct detailed analyses, and troubleshoot issues through a conversational interface. Phaidra Factory provides specialized AI agents that autonomously optimize cooling systems and power allocation at gigawatt scale. Both products are built on reinforcement learning and feed-forward control technology, with Prism providing observability and Factory providing autonomous control. The platform achieves approximately 80% reduction in thermal spikes while enabling higher TCS temperatures for improved energy efficiency.
