Raidium is developing a foundation model for precision medicine in radiology, aiming to advance access to imaging biomarkers through an AI-native interactive platform. Their approach utilizes multimodal input capabilities and self-supervised learning, allowing the model to perform various downstream medical analyses beyond a single task. The company was founded by Paul Hérent (CEO) and Pierre Manceron (CSO), both with prior experience at Owkin. Raidium has secured significant funding, including a €16 million seed round, and has received recognition such as the AMGEN Golden Ticket and being named a Future 40 startup by Station F. Their core product, ONCOPILOT, is a promptable CT foundation model for solid tumor evaluation, demonstrating state-of-the-art performance in tumor segmentation and radiologist-level precision in RECIST 1.1 evaluations.
