About Phaidra
phaidra.aiPhaidra builds AI agents for “AI factories” — software that autonomously orchestrates cooling, power and workload management to optimize efficiency and performance. Their technology is designed to maximize tokens produced per watt, cutting energy costs and boosting utilization for large-scale model training and inference. Phaidra’s agents integrate with datacenter infrastructure and orchestration stacks to make real‑time thermal, power and scheduling decisions. The result is higher throughput, lower total cost of ownership, and more sustainable, high-density AI compute operations.
