Sygaldry Technologies, a startup in Ann Arbor, has raised $105M in a Series A led by Breakthrough Energy Ventures, following a $34M seed from Initialized Capital. The company is building quantum-accelerated AI servers to meet the $5.2T in AI infrastructure investment projected through 2030. The Series A was led by Initialized. Additional investors include Y Combinator, Rock Yard Ventures, IQT, the University of Michigan, Expeditions Fund, 468 Capital, Morpheus Ventures, WTI, Overmatch Ventures, and RRE Ventures. The firm argues that quantum computing can provide targeted acceleration for the AI algorithms that are hardest to run efficiently on classical hardware.
