About the company Raidium is building a foundation model for precision medicine in radiology. Our first release, Curia, is already state of the art. We aim to broadly democratize access to imaging biomarkers for both clinical and research applications through a biomarker factory. Our model is embedded in a new type of solution for the radiologist that enables a revolutionary AI-native workflow. Thanks to a 16M€ seed round raised in November 2024, Raidium is expanding its team. The team The founders of Raidium are experts in radiology and machine learning from Owkin, bringing together extensive experience from both fields.
