Founded in 2019 by Jim Gao, who previously designed the cooling systems that remove heat from the servers in Google's data centers, Phaidra pairs deep AI expertise with mission-critical facility experience. Its mission is to transform AI factories from cost centers into dynamic, revenue-generating powerhouses by maximizing every watt of performance.
