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.
Gavin Uberti
Gavin Uberti is the co-founder and CEO of Etched, a Cupertino-based AI chip startup building the world's first transformer-specific ASIC called Sohu. A Harvard dropout and 2024 Thiel Fellow, Uberti co-founded Etched in 2022 alongside Chris Zhu and Robert Wachen after betting that transformer architecture would dominate AI for years to come. That bet has paid off spectacularly: Etched has raised over $625 million (including a $500M round in January 2026 at a $5 billion valuation), and Sohu claims to run transformer inference 20x faster than Nvidia's H100 at a fraction of the cost - positioning Etched as one of the most serious challengers to Nvidia's dominance in AI compute.
