Snowcap Compute develops a superconducting computing platform that operates at 4.5 Kelvin using Josephson Junctions instead of semiconductor transistors, achieving five orders of magnitude less energy per switch and zero-resistance wires. The platform employs standard 300mm semiconductor fabrication processes and helium-based cryogenic infrastructure already used in quantum computing deployments. It supports standard digital chip designs including CPUs, GPUs, and AI inference accelerators, allowing partners to port existing designs. The company targets data centers handling AI and high-performance computing workloads to address power and performance limits of silicon. Snowcap Compute raised $23 million in a seed funding round led by Playground Global. Leadership includes Mike Lafferty as CEO with prior experience at Cadence and Agere, Anna Herr as CSO from Northrop Grumman and imec, and other executives from Intel, Apple, and NVIDIA.
