What Simago does

Simago is a French network of liberal (independent) medical imaging centers that organizes 370 radiologists across 125 exercise locations and 30 Professional Exercise Companies (SELs), managing 5.3 million patient appointments annually through a fleet of 163 MRI and CT scanners. Radiologists join as physician-associates and retain majority ownership — holding approximately 60% of the head-company capital and 75%+ in individual SELs — while minority financing is provided by private equity firm Ardian. The network operates under France's national health insurance (CPAM) fee schedule and provides collective services including central PACS infrastructure, procurement leverage, shared administrative functions, and continuing education through Simago Academy (50+ courses).

The technology stack is anchored by a central PACS unifying imaging archives across all centers, enabling cross-site data sharing and AI integration. The October 2025 Gleamer partnership deploys AI diagnostic assistance across all imaging modalities (X-ray, CT, MRI, mammography), with a stated goal of directing 90% of patients to an AI solution within the year. Digital patient intake is delivered through WiiS kiosks at 12 sites, AI telephony through Vocca, and teleradiology services through the wholly-owned subsidiary Alliance Téléimagerie (~100 radiologists, 80% interpretations completed under 12 hours). The SimaRempla mobile application (launched April 2026) addresses workforce continuity through replacement management, and the Simago Academy platform delivers 24/7 training across all modalities.

The business model combines network association economics (radiologists share in collective profitability, procurement, and shared services) with transactional revenue from medical imaging procedures billed through the French national system. The GTM motion is community-led and sales-supported, targeting radiologists seeking to preserve independence while gaining network benefits, plus young radiologists seeking association without initial capital outlay. A 47-person direction team provides central operational support. Geographic footprint spans 11 French regions and DROM (overseas territories), with two pilot centers in Italy and the 2025 launch of Astérion, a parallel nuclear medicine network operating with its own governance.

Revenue model

1. Network Association Fees / Value Sharing: Radiologists join as liberal physician associates (non-salaried). Revenue is generated through shared profitability of imaging center activities. Radiologists retain independence and share in the benefits of the network's collective purchasing power, shared services, and operational support.
2. Medical Imaging Services Revenue: The network's imaging centers generate revenue through medical imaging procedures (X-rays, CT, MRI, mammography, interventional radiology) billed to patients and public/private insurers under France's national health insurance system.
3. Teleradiology Services: Alliance Téléimagerie provides remote radiology interpretation services to network centers and external healthcare facilities, generating service fees for interpretation work.
