Raidium

Raidium is a Paris-based French medical-imaging startup founded in 2022. The company focuses on artificial intelligence for radiology, particularly the analysis of three-dimensional computed tomography (CT) scans and magnetic resonance imaging (MRI). Its technology is described as combining foundation models for medical images with an interactive radiology viewer. The intended system supports image interpretation, extraction of imaging biomarkers, and integration into clinical workflows and clinical trials. The company operates in a field where medical-imaging software is increasingly being developed to help radiologists handle large and complex datasets. Rather than presenting itself solely as a narrow algorithm for one finding or disease, Raidium’s stated approach centers on broader models trained for three-dimensional imaging modalities. These models are intended to provide a common technical foundation for multiple radiology applications, while the viewer gives users a way to inspect images and work with derived measurements or biomarkers. Raidium’s potential use cases include radiological image analysis, quantitative assessment of disease, and the generation of imaging-derived data for research and clinical development. The company’s focus on biomarkers also connects its platform to clinical-trial workflows, where reproducible measurements from scans can support patient stratification, treatment assessment, and study endpoints. The available reference material does not establish the precise regulatory status, commercial availability, hospital customer base, or geographic operating footprint of individual Raidium products. The startup received several forms of recognition during its early development. In 2023, it won Amgen France’s first Golden Ticket competition held at BioLabs Hôtel-Dieu in Paris. In 2024, it received the Grand Prix of the French government’s i-Lab innovation contest and was selected for the European Innovation Council’s EIC Accelerator programme. It was also named among Station F’s Future 40 startups in 2024. In 2025, Raidium won the AI for Health challenge organized by the Île-de-France Region and Hôpital Fondation Adolphe de Rothschild. In 2024, Raidium announced a €16 million seed financing round. The round was backed by investors including Newfund and the European Innovation Council Fund. This financing provided capital for the development of its imaging foundation models, viewer, and broader clinical applications. The available sources do not identify a current chief executive, other executives, detailed ownership percentages, revenue, valuation, or listed securities. Raidium remains a private company and is presented in the reference material as an active medical-AI startup.

Raidium was founded in France in 2022 as a startup focused on artificial intelligence for medical imaging. From its base in Paris, the company developed an approach centered on foundation models for three-dimensional radiology data, with particular attention to CT and MRI scans. The company’s stated technology combines these models with an interactive radiology viewer, allowing users to examine medical images and obtain imaging biomarkers for use in clinical work and clinical research. The early development period was marked by recognition from French and European innovation programmes. In 2023, Raidium won Amgen France’s first Golden Ticket competition at the BioLabs Hôtel-Dieu facility in Paris. This recognition placed the young company within a biomedical innovation ecosystem and helped distinguish its work in the emerging medical-AI sector. In 2024, Raidium received the Grand Prix of the French government’s i-Lab innovation contest. The same year, it was included in Station F’s Future 40 selection, which highlights high-growth startups associated with the Paris startup campus. Raidium was also selected for the European Innovation Council’s EIC Accelerator programme. These distinctions reflected interest in its attempt to build reusable AI infrastructure for radiology rather than a single-purpose diagnostic application. Later in 2024, the company announced a €16 million seed round. Newfund and the European Innovation Council Fund were among the named backers. The round represented an important financing milestone for a company still in its early growth phase and was intended to support continued development of its models, imaging viewer, and clinical applications. Publicly available reference material does not provide a detailed breakdown of the financing, the company’s valuation, or its ownership structure. In 2025, Raidium won the AI for Health challenge organized by the Île-de-France Region and Hôpital Fondation Adolphe de Rothschild. This award further associated the company with regional healthcare innovation and clinical applications of artificial intelligence. Raidium’s historical trajectory therefore remains that of an early-stage medical-technology company: formation in 2022, recognition through French and European innovation programmes, development of a platform for CT and MRI analysis, and seed financing to expand its technology. The available material does not establish whether its software has obtained specific regulatory clearances, reached broad commercial deployment, or been adopted by named hospitals or pharmaceutical companies.

  Raidium founded

  [1]Raidiumen.wikipedia.org

  Raidium was founded in France as a startup focused on artificial intelligence for radiology and medical imaging.

Raidium positions itself as a medical-AI company building general-purpose or foundation-model infrastructure for three-dimensional radiology, rather than focusing only on a single diagnostic algorithm. Its platform-oriented approach links image interpretation, interactive visualization, quantitative biomarker extraction, clinical workflows, and clinical-trial use cases.
