Sygaldry Technologies, a quantum computing company headquartered in Michigan, announced a $139 million injection of venture capital to build out its solution. The raise consisted of a $34 million seed round led by Initialized Capital and a $105 million Series A led by Breakthrough Energy Ventures.

The company aims to leverage quantum computing to drastically expedite AI training and inference. Sygaldry’s servers combine multiple qubit types within one fault-tolerant architecture, providing the necessary scale and speed to support advanced AI applications at an attainable cost. 

“We are working at the frontier of quantum and AI simultaneously, because we believe their intersection will define the next era of computing,” Michael Keiser, Sygaldry’s co-founder, said in a statement. “Our technology will accelerate the classical algorithms AI teams already rely on. In parallel, we are developing entirely new quantum-native approaches to AI that classical systems simply cannot match.”
