Earth Venture Capital invests in Sygaldry Technologies
Global climate deeptech venture capital firm Earth Venture Capital has announced its participation in a $139-million investment round in Sygaldry Technologies, which builds quantum-accelerated AI servers to speed up training and inference.
Earth Venture Capital invested in both the company’s $34-million seed round and $105-million Series A.
The company is building quantum-accelerated AI servers designed to significantly reduce the energy and cost required to train and operate large AI models—a critical challenge for Asia’s rapidly expanding AI infrastructure.
The Series A was led by Breakthrough Energy Ventures, following the earlier seed round led by Initialized Capital.
Led by quantum veteran Chad Rigetti and AI scientist Michael Keiser, Sygaldry is developing servers that combine multiple qubit types within a single fault-tolerant architecture. Unlike traditional quantum companies racing to scale a single-qubit approach, Sygaldry’s multi-qubit system is purpose-built for AI workloads and designed to operate within existing data centre infrastructure.
Earth VC said its continued backing reflects early conviction in Sygaldry’s approach and aligns with its strategy of bridging global deeptech innovation with Asian market needs, particularly in energy-efficient AI.
