What FieldLine does
FieldLine Inc. is a privately held, Boulder, Colorado-based medical device company founded in 2019 that develops and sells the HEDscan system, a non-invasive, wearable magnetoencephalography (MEG) brain imaging device based on optically-pumped magnetometer (OPM) quantum sensor technology. Small quantum sensors leveraging atomic spin principles are placed directly on the head inside a lightweight, wearable helmet that accommodates all ages and head sizes, from infants to adults, enabling high-fidelity mapping of neural activity without requiring cryogenic cooling. The platform supports up to 512 sensors in a scalable configuration and is designed to operate at room temperature in any room of a medical facility, eliminating the dedicated shielded rooms and liquid-helium infrastructure that traditional SQUID-based MEG systems require.
The company's product portfolio centers on HEDscan and is complemented by Magnetic Shields for environmental interference isolation and High Density Helmets for high-density sensor configurations. Target customers are healthcare providers, medical imaging centers, and research institutions — including universities conducting neuroscience research, cognitive neuroscience studies, epilepsy monitoring, and brain-computer interface development. FieldLine distributes through direct enterprise sales to hospital systems and research buyers, supported by installation, training, and ongoing technical services. Pricing is quote-based and not publicly disclosed, consistent with capital medical equipment sales. No regulatory clearances, certifications, or named customer references are disclosed in the source material.
The company is founder-owned and operated by three co-founders — Orang Alem (CEO), Svenja Knappe (PhD physicist and University of Colorado Boulder faculty member), and Jeramy Hughes — each with multi-decade backgrounds in atomic physics, OPM miniaturization, and quantum device commercialization. FieldLine has not disclosed institutional venture funding; its only reported external funding event is an October 2025 BIRD Foundation grant (a U.S.-Israel bilateral R&D program). The company currently operates only in the United States.

FieldLine competitors and assessment
Company assessmentBroad incumbents
- Magstim: Established neuroscience equipment manufacturer best known for transcranial magnetic stimulation (TMS) systems, also active in MEG-adjacent research tools. Serves overlapping neuroscience research and clinical customers with a broader neuromodulation portfolio.
- Compumedics: Diversified neurodiagnostics and sleep-medicine device company offering EEG, PSG, and brain-monitoring systems. Sells into overlapping neurology and clinical-research customer accounts, though its product portfolio is much broader than FieldLine's MEG focus.
Emerging players
- Kernel: Developer of wearable brain-imaging and brain-measurement devices (e.g., Kernel Flow TD-fNIRS) targeting cognitive performance and clinical research. Targets a partially overlapping customer base with a different optical rather than magnetic sensing modality.
- Soterix Medical: Specializes in non-invasive neuromodulation and brain-stimulation devices (tDCS, tACS, HD-tDCS) used in clinical trials and neuroscience research. Sells into overlapping neurology and brain-research customer accounts, though focused on stimulation rather than imaging.
Others
- Blackrock Microsystems: Provider of neural recording systems, electrode arrays, and brain-computer interface (BCI) tools used in neuroscience and clinical research. Adjacent to FieldLine through shared BCI-application customers, though focused on invasive electrophysiology rather than MEG.
- Brain Products: Leading manufacturer of EEG caps, amplifiers, and neuroimaging accessories used in neuroscience and clinical research. Serves many of the same research customers as FieldLine and is often deployed alongside MEG in multimodal brain-imaging studies.
- Neuralink: High-profile developer of invasive brain-computer interface implants. Operates in the same broader brain-interface space as FieldLine and shares the long-term vision of high-bandwidth neural interfaces, but takes a fundamentally different (invasive) technical approach.
- Synchron: Clinical-stage brain-computer interface company developing endovascular neural implants for patients with paralysis. Tangentially related through the broader BCI market that FieldLine's wearable MEG also serves for non-invasive neural recording.
Direct peers
- MEGIN (Elekta MEG): Incumbent provider of SQUID-based MEG systems with the largest installed base globally in hospitals and research institutions. Competes with FieldLine for the same magnetoencephalography use cases, representing the established technology FieldLine is displacing.
- Cerca Magnetics: Commercializes OPM-based wearable MEG systems derived from University of Nottingham research, with the same core value proposition as FieldLine: wearable, room-temperature, cryogenic-free magnetoencephalography. Directly competes for the same clinical and research customers.
