Sygaldry Technologies is an Ann Arbor-based startup building quantum-accelerated AI servers designed to operate alongside classical infrastructure within data centers, exponentially speeding up critical AI algorithms while reducing cost and power consumption. Founded in 2024 by Chad Rigetti (founder of Rigetti Computing), Idalia Friedson, and Michael Keiser, the company integrates quantum hardware directly into AI workflows rather than treating quantum as a standalone system. YC-backed with $139M raised across seed and Series A, Sygaldry is developing both quantum-accelerated classical algorithms and entirely new quantum-native approaches to AI.
