The firm said the latest injection brings the company’s total venture backing to approximately $270 million.
The raise comes as the company reports annual revenue growth of over 130%, driven by enterprise adoption of its Solar large language model and document intelligence offerings.
Proceeds from the round will be used to further develop its proprietary foundation models, expand into key markets including the US and Japan, and hire talent to support its next phase of growth.
