What MAG4HEALTH does
MAG4Health is a French MedTech startup spun off from CEA-Leti in 2021, developing room-temperature Magnetoencephalography (MEG) brain imaging systems based on proprietary Helium-4 Optically Pumped Magnetometer (4He OPM) quantum sensors. The core sensing technology was originally developed for the European Space Agency's Swarm mission (launched 2013) to map Earth's magnetic field, giving MAG4Health an unusual provenance for a MedTech venture. The system integrates 16-96 sensors in a flexible wearable helmet that adapts to any head size from infants to adults, with sensors placed 1-3 mm from the scalp versus ~2 cm for conventional systems. Supporting subsystems include a proprietary auto-localization algorithm, acquisition software, and an innovative sliding magnetically shielded room. Differentiated performance features include bandwidth exceeding 1 kHz, dynamic range up to 200 nT, low power dissipation (1 W per 50-sensor array), and a sensor lifespan validated at over 10 years via accelerated ageing tests and space heritage.
The company sells directly to hospitals, universities, and clinical research institutions through enterprise field sales, with installation, calibration, and ongoing support managed by MAG4Health engineers. The OPM-MEG system is currently marketed exclusively as a Research System; the company has no FDA or CE medical-device approvals, with regulatory work actively in progress. Revenue models combine hardware sales (custom-configured research systems on multi-year contracts) and collaborative clinical research services, with no publicly disclosed pricing. The current customer base spans approximately 8 installations and collaborations across France (University Hospitals Lyon, Marseille, Amiens), the UK (Aston University), the USA (Henry Ford Health Institute), and Japan (NICT), with applications focused on epilepsy localization, pre-surgical functional brain mapping, neurological disorder research, and cognitive neuroscience.
MAG4Health employs roughly 20 staff, founded and led by three PhDs (CEO Matthieu Le Prado, CMO Etienne Labyt, CTO Agustin Palacios-Laloy) carrying combined patent portfolios in quantum sensing and neurophysiology. The company is headquartered in Grenoble, France (SAS entity, share capital €101,549.36). Total disclosed funding is approximately €7.2 million across a 2021 round and a July 2023 €5.3 million round led by French public and private investors including Bpifrance, Grenoble Angels, BADGE, Critical Path Ventures, Angelor/33 Californie, with additional support from regional authorities (Region AURA, LyonBiopole). The strategic board includes former Philips Healthcare CEO Michèle Lesieur as advisor.

MAG4HEALTH product offering
Product offeringCore offering
MAG4HEALTH develops, manufactures, and sells optically pumped magnetometer (OPM) magnetoencephalography (MEG) brain imaging systems based on proprietary Helium-4 quantum sensors. The integrated platform provides non-invasive, room-temperature brain activity recording for clinical diagnostics (notably epilepsy pre-surgical mapping) and neuroscience research. The offering combines a wearable sensor helmet, acquisition electronics, reconstruction software, and optional magnetically shielded room accessories, sold as turnkey imaging installations to hospitals and universities.
Product overview
MAG4Health offers a unified OPM-MEG brain imaging system built around proprietary Helium-4 quantum sensors. The core product is the OPM-MEG System, which integrates room-temperature quantum sensors (Helium-4 OPM) developed from space technology into a wearable helmet design. Supporting components include user-friendly acquisition software with auto-localization capabilities and an innovative sliding magnetically shielded room. Data export uses the FIFF format for compatibility with standard neuroscience analysis tools. The company notes the system is currently offered as a Research System without medical or regulatory approvals.

Direct peers
- York Instruments (Cerca / York Magnetics): York Instruments develops MEG systems (historically SQUID-based, evolving toward OPM) for clinical and research use. It competes directly in the same brain-imaging equipment category and customer segment.
- FieldLine Inc: FieldLine is a US-based developer of OPM-based MEG systems for neuroscience and clinical applications. It targets the same customer base (hospitals, research institutions) with a similar quantum-sensor value proposition.
- Cerca Magnetics: Cerca Magnetics is a UK-based spin-out from the University of Nottingham that develops OPM-MEG systems targeting similar research and clinical neurology customers. It is the most direct OPM-MEG competitor with comparable wearable helmet architecture.
Others
- CEA-Leti: CEA-Leti is the French research lab from which MAG4Health was spun off in 2021. It is comparable as the technology origin and ongoing research partner rather than a direct competitor.
- Brainbox Ltd: Brainbox is a UK-based neuroimaging solutions provider and academic partner in MEG research. Comparable as an adjacent service provider that supports MEG research sites similar to MAG4Health's installation partners.
Broad incumbents
- MEGIN (formerly Elekta MEG): MEGIN is the established SQUID-based MEG system provider and the current market leader in clinical MEG. It competes with MAG4Health's OPM-MEG across the same clinical neurology use cases but with legacy cryogenic technology.
- Elekta: Elekta is a global medtech incumbent in radiation therapy and neuroscience that historically owned the MEG business (now MEGIN). It is comparable as a large neurology/oncology adjacent player with overlapping hospital customers.
