Great Sky

Great Sky is a photonics and AI computing company that builds hardware from first principles to approach the physical limits of intelligence. The company develops superconducting neural networks that compute with superconductors and communicate with light, processing text, audio, and video a million times faster than human perception with the power consumption of a single compute rack. Great Sky technology addresses the fundamental limitation of conventional chips, which were designed for mathematical calculations rather than intelligence and consume energy orders of magnitude beyond biological intelligence when used for AI. The company systems are designed for applications including universal assistants serving millions of simultaneous users, fusion energy plasma instability prediction, molecular simulations for individualized medicine, physical modeling, national security signal processing, and personal AI with adaptive weights. Founded in 2024 and headquartered in Boulder, Colorado, Great Sky has raised approximately $42.9 million in seed funding from investors including Bison Ventures, Matchstick Ventures, and Range Ventures.
