## About Raidium

## Company Overview
- **One-liner**: Raidium builds an AI-native interactive platform that uses foundation models to advance precision radiology, enabling radiologists to detect lesions, generate RECIST-ready reports, and accelerate clinical workflows.
- **Entity Type**: Private (Seed stage; $22.1M total funding including grant and venture rounds)
- **Headquarters**: Paris, France
- **Founded**: 2022
- **Founders**: Paul Hérent (MD, MSc, CEO) and Pierre Manceron (MSc, CSO)

## Core Business
- Primary industry: Medical imaging AI / Healthcare IT
- Target customers: Radiologists, hospitals, clinical research organizations (B2B, Enterprise)

## Products & Services
- **[Raidium Read](https://raidium.eu/about-us/)**: AI-native viewer for oncology that detects solid tumors, new lesions, and incidental findings; segments organs and lesions; and produces structured RECIST 1.1–ready reports within a single interface. (SaaS / Software)
- **[Jolia](https://linkedin.com/company/raidium)**: Vision-language foundation model for chest and abdominal CT, trained on 74,434 CT–report pairs using the ConQuer alignment method. Achieves state-of-the-art findings classification (77.05% average AUROC) and abdominal CT report generation (+34% relative gain on RadGraph-F1). (Foundation model / API)
- **[ONCOPILOT](https://raidium.eu/about-us/)**: AI model for automated solid tumor evaluation, delivering radiologist-level precision in RECIST 1.1 measurements and reducing variability. (AI model)

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding of $22.1M (including a €16M seed round co-led by Kurma Partners and Newfund, a €2.5M EIC Accelerator grant, and other rounds)
- **Notable Investors/Partners**: Kurma Partners, Newfund, Galion.exe, Founders Future, Debiopharm, Techmind, European Innovation Council (EIC), Bpifrance, Inria, Microsoft (via GenAI Studio), Centre d’Imagerie du Nord

## Competitive Advantages
- Proprietary foundation models (Curia for structural understanding, Jolia for vision-language) trained on large, diverse datasets.
- First AI-native PACS viewer that integrates detection, segmentation, and structured reporting into one semi-automated workflow — avoiding the “tool trap” of fragmented point solutions.
- Strong sovereign AI positioning (French government backing, partnerships with Inria and Bpifrance).
- Access to large retrospective real-world datasets via hospital partnerships.

## Strategic Focus
- Deploy Raidium Read to market and scale commercial adoption.
- Continue advancing foundation model capabilities (e.g., Jolia, ONCOPILOT) for broader clinical applications.
