Earth VC Backs Quantum AI Startup Sygaldry in $139M Funding Round

Gate News message, April 17 — Earth Venture Capital, a Vietnam-based climate tech VC, invested in quantum AI startup Sygaldry Technologies across both its $34 million seed round and $105 million Series A, bringing total funding to $139 million.

Sygaldry, with offices in Ann Arbor and San Francisco, is developing hybrid servers that integrate quantum components with GPU infrastructure for AI training and inference. The company aims to reduce power consumption for AI workloads. Earth VC was the only Asia-based investor alongside Y Combinator and Initialized Capital.

Sygaldry was co-founded by Chad Rigetti, who previously founded Rigetti Computing and took it public via IPO. The startup's hybrid quantum architecture combines multiple qubit types within a fault-tolerant system designed to maintain accuracy when components fail, targeting AI-specific workloads rather than general-purpose quantum computing.
