Fabric Cryptography
Fabric Cryptography is a San Francisco hardware startup building the Verifiable Processing Unit (VPU) - a fully programmable custom-silicon chip with an instruction set designed specifically for advanced cryptography. Founded in 2021 by Michael Gao, Tina Ju, and Sagar Reddy, Fabric aims to do for cryptography what Nvidia did for AI: dramatically accelerate workloads like zero-knowledge proofs, fully homomorphic encryption, and multi-party computation compared with CPUs, GPUs, and fixed-function accelerators. The company has raised $39M total, including a $33M Series A in August 2024 co-led by Blockchain Capital and 1kx.
Xvisio Technology Corporation
Xvisio Technology Corporation is a Silicon Valley-founded spatial computing company building the visual SLAM engines, sensor-fusion modules, and mixed-reality hardware that let machines and headsets understand where they are in physical space. Its SeerSense modules and SeerLens MR glasses - built on a low-latency VPU pipeline it calls SlimEdge XR - power 6DoF tracking, depth sensing, and on-device AI inferencing for AR headsets, robots, and industrial devices across healthcare, manufacturing, education, and logistics.
