About

Sygaldry Technologies develops quantum-accelerated AI servers, building hybrid quantum-classical systems that combine multiple qubit modalities within a fault-tolerant architecture. The company's stated goal is to provide exponential compute speedup for AI training and inference, while reducing cost and energy consumption relative to conventional approaches.

The company operates at the intersection of quantum computing and artificial intelligence, with technical work spanning quantum computing, hybrid quantum-classical systems, and fault-tolerant quantum architecture. Sygaldry has raised $139 million in Series A and Seed funding and participated in Y Combinator's Spring 2025 cohort.

Sygaldry is headquartered in Ann Arbor, Michigan, with an additional presence in San Francisco, California.
