Great Sky builds AI hardware that dramatically increases speed and energy efficiency for large-scale AI compute. It combines photonics for single-photon optical communication, superconducting electronics for ultra-fast low-power circuits, and semiconductor components to co-locate processing and memory, reducing data movement. The company positions itself as a B2B hardware provider designing systems at the physics layer to push beyond incremental improvements in existing accelerators. Its technology stack includes integrated photonics, superconducting circuits, and semiconductor memory/logic, targeting cloud providers and AI infrastructure operators. Great Sky aims to address the scaling limits of current AI accelerators by delivering orders-of-magnitude improvements in performance per watt.
