Phaidra, a company focused on building AI agents to manage and optimize data centers built for AI workloads, has announced a Series B funding round exceeding $50 million. The round was led by Collaborative Fund, with participation from Helena, Index Ventures, NVIDIA, Sony Innovation Fund, and other strategic investors.
The company is tackling a fundamental challenge in the age of artificial intelligence: energy constraints. As AI workloads grow, so does the power demand. The ability to generate intelligence—and the revenue it drives—is increasingly limited by the energy available to run these massive computing systems. Phaidra’s goal is to maximize the output of every watt consumed, turning energy into tokens of intelligence with greater precision and efficiency.
Modern AI factories rely on a complex mix of power systems, cooling infrastructure, and workload management tools. Historically, these components have operated in silos, with minimal coordination. This fragmented approach leads to significant inefficiencies, especially in environments where energy is a scarce and valuable resource. Phaidra’s solution is to unify these systems through intelligent orchestration, treating the entire facility as a single, integrated system.
To achieve this, Phaidra is developing a suite of AI agents trained to manage everything from liquid cooling systems to chiller plants and workload distribution. These agents are designed to outperform traditional control logic and human intuition, unlocking levels of efficiency that were previously unattainable. The company is already working with industry leaders like NVIDIA to design the next generation of AI infrastructure, positioning itself at the forefront of innovation in this space.
With the new funding, Phaidra plans to accelerate the development of its agent ecosystem, deepen its collaboration with NVIDIA, and expand its reach to more global operators. As demand for AI infrastructure continues to surge, Phaidra’s technology offers a path to smarter, more sustainable data center operations—making it a key player in the future of intelligent computing.
How the funding will be used: This funding will be used to advance Phaidra’s mission of making AI factories radically more resource-efficient.
KEY QUOTES:
“Every breakthrough in AI requires an equally ambitious breakthrough in infrastructure efficiency. Our technology enables AI data centers to run smarter, not just harder, cutting costs while dramatically reducing their environmental footprint.”
Jim Gao, CEO of Phaidra
“Collaborative Fund has always believed that the most transformative companies are those that marry profit with purpose. Phaidra is tackling AI’s biggest bottleneck, energy consumption, in collaboration with NVIDIA, the global leader in compute.”
