Sygaldry Raises $139M for Quantum-Accelerated AI Servers

Sygaldry Technologies raised $139M in Series A and Seed financing to build quantum-accelerated AI servers. The company’s Series A totals $105M and was led by Breakthrough Energy Ventures, following a $34M seed round led by Initialized Capital.

Sygaldry says its servers are designed to speed up critical AI algorithms while reducing the cost and power needed to train and run large models. The company is led by quantum computing pioneer Chad Rigetti and aims to operate quantum processing alongside classical data-center infrastructure.
