RadixArk raised $100 million in a seed funding round. The investment values the startup at $400 million. Accel and Spark Capital co-led the financing.
Nvidia’s venture arm, NVentures, participated in the round. Broadcom CEO Hock Tan also joined as an investor. Former xAI engineer Ying Sheng founded the company.
