Sygaldry

Sygaldry Technologies builds quantum-accelerated AI servers — augmenting classical data-center infrastructure with quantum processors purpose-built for AI to deliver exponential speedups on specific training and inference tasks. Founded in 2024 in Ann Arbor, Michigan by Chad Rigetti (founder of Rigetti Computing), Idalia Friedson, and Michael Keiser, the company combines multiple qubit types within a single fault-tolerant architecture to accelerate model training, fine-tuning, and token generation while cutting compute cost and energy use. A Y Combinator Spring 2025 company, Sygaldry has raised $139M ($34M seed led by Initialized Capital and a $105M Series A led by Breakthrough Energy Ventures, with Bloomberg Beta among its investors). Sygaldry currently publishes no public developer API; this profile is maintained for API Evangelist network discovery.

Sygaldry is profiled on the APIs.io network. Tagged areas include Company, Quantum Computing, Artificial Intelligence, AI Infrastructure, and Hardware.
