# Akash Systems

> Akash Systems is a San Francisco deep-tech company building chips and systems cooled by lab-grown diamond. Its patented GaN-on-Diamond technology pulls heat away from transistors at the nanometer scale, powering everything from CubeSat radios that beam data at 5 Gbps to AI servers that run cooler at higher density. Backed by Khosla Ventures, Founders Fund and the U.S. CHIPS Act, the company is building a 40,000 sq ft diamond-semiconductor fab in West Oakland.
