Akash Systems, Inc. is a venture-backed, late-stage, Bay Area company that makes and sells Diamond Cooled GPU-based servers to AI companies, Cloud Service Providers, and data centers worldwide. The deep tech company pioneered Diamond Cooling® technology wherein the world’s most thermally conductive material, lab-grown diamond, is brought into intimate contact with GPUs – the densest heat source chip in a modern high compute server. The resulting Akash server is one that exhibits more compute in FLOPS (>50%) and FLOPS per Watt (by 2x) than any other server in the market today. Akash’s Diamond Cooled servers also reduce the energy cost of cooling the entire data center since the servers can operate in an ambient temperature of up to 120oF. The company’s lead investors include Khosla Ventures and Founders Fund. Akash Systems recently deployed its Diamond Cooling® technology in space, where many Akash satellite radios are now in operation.
