Chad Rigetti<\/a> started Rigetti Computing in Berkeley in 2013 after leaving IBM\u2019s quantum research labs. Over almost ten years, he built it into one of the few public companies focused only on quantum technology. He led the company through Y Combinator<\/a>, raised major venture capital, and took it public on Nasdaq through a SPAC in 2022. When the company struggled to commercialise its technology, he stepped down as CEO. In 2024, he started a new company.<\/p>\n

Sygaldry Technologies, his new company founded in the US, announced $139 million in funding. The funding includes a $105 million Series A round led by Breakthrough Energy Ventures<\/a> in March 2026, following a $34 million seed round backed by Initialized Capital. <\/p>\n

This time, the focus is clearer: building quantum hardware for AI data centres to help lower the high energy costs of training and running large AI models.<\/p>\n

Unlike IonQ<\/a>, PsiQuantum<\/a>, and Quantinuum<\/a>, Sygaldry focuses solely on AI infrastructure. The company wants to make data centres more efficient rather than trying to solve every quantum computing problem. This specific goal gives Sygaldry a clearer business direction.<\/p>\n

Sygaldry plans to build servers that combine quantum and traditional hardware within the same data centre. This setup lets AI developers use quantum-accelerated algorithms with their current tools and, eventually, create AI methods made just for quantum computing.<\/p>\n","protected":false},"excerpt":{"rendered":"Chad Rigetti started Rigetti Computing in Berkeley in 2013 after leaving IBM\u2019s quantum research labs.
