TLDR: Phaidra, a company specializing in AI agents for optimizing data center infrastructure, has successfully closed a Series B funding round exceeding $50 million. Led by Collaborative Fund, with significant participation from investors including NVIDIA and Sony Innovation Fund, this capital infusion will accelerate Phaidra’s mission to enhance the energy efficiency and performance of ‘AI factories’ through its intelligent control systems.
Phaidra, a pioneer in developing AI agents for the optimization of data center infrastructure, has announced the successful closure of a Series B funding round, raising over $50 million. The round was spearheaded by Collaborative Fund, with notable participation from a diverse group of investors including Helena, Index Ventures, NVIDIA, Sony Innovation Fund, Starshot Capital, Section 32, Flying Fish, Ahren Innovation Capital, and Character. Additionally, prominent individual investors such as Mustafa Suleyman and Mark Cuban joined the round. This latest investment brings Phaidra’s total lifetime funding to approximately $120 million, following a $25 million Series A round in July 2022.
The funding is earmarked to accelerate Phaidra’s core mission: building the ‘AI Factories of the Future’ by making data center infrastructure, purpose-built for AI workloads, radically more resource-efficient through advanced AI agents. The company aims to maximize the ‘tokens generated by every watt of energy’ that powers these large-scale computing systems, a critical objective in an energy-constrained world.
Phaidra addresses the inherent inefficiencies in modern AI factories, where complex power, cooling, and workload management systems often operate independently. Their solution is an AI-powered virtual plant operator named ‘Alfred,’ which seamlessly integrates into existing industrial control systems using standard protocols like BACnet and OPC-UA. Alfred continuously monitors thousands of sensor signals in real-time, employing reinforcement learning to predict equipment behavior and automatically adjust setpoints for components like valves, pumps, and fans to maintain optimal performance and reduce energy consumption.
Jim Gao, CEO of Phaidra, emphasized the critical need for such innovation, stating, “Every breakthrough in AI requires an equally ambitious breakthrough in infrastructure efficiency.” He added, “Our technology enables AI data centers to run smarter, not just harder, cutting costs while dramatically reducing their environmental footprint.”
The company is actively collaborating with industry leaders like NVIDIA to design the next generation of AI infrastructure. This partnership is crucial as Phaidra develops a portfolio of AI agents for various functions, from liquid cooling and chiller plant management to workload optimization, orchestrating complex systems beyond human intuition or hard-coded logic.
Sophie Bakalar, Partner at Collaborative Fund, highlighted the strategic importance of Phaidra’s work: “Phaidra is tackling AI’s biggest bottleneck, energy consumption, in collaboration with NVIDIA, the global leader in compute.”

With the new capital, Phaidra plans to accelerate the development of its agent ecosystem, deepen its collaboration with NVIDIA, and expand its reach to additional global operators. The company operates on a B2B software-as-a-service (SaaS) model, offering subscriptions to its AI control system. This model delivers significant operational savings, typically achieving 10-30% efficiency improvements that can offset subscription fees within months. Phaidra benefits from high customer retention, as its reinforcement learning approach continuously improves efficiency over time. Future revenue expansion is expected as customers deploy the system across more facilities or extend coverage to new equipment types.
