Sygaldry raises $139M to build quantum computers for AI

ANN ARBOR, Mich., April 14, 2026 (GLOBE NEWSWIRE) -- Sygaldry Technologies, Inc. announced today that it has raised $139M in Series A and Seed financing to build quantum-accelerated AI servers. The $105M Series A in March 2026 was led by Breakthrough Energy Ventures, following a $34M seed round led by Initialized Capital. Sygaldry's servers aim to exponentially speed up critical AI algorithms, reducing the cost and power needed to train and operate increasingly large models.

"We're building quantum computers that meet the specific requirements for AI processing, with the goal of enabling a fundamentally more efficient way of converting megawatts into intelligence," said Sygaldry CEO and co-founder Chad Rigetti.

Demand for more cost- and energy-efficient AI infrastructure is soaring. An ...
