Soterix Medical, Inc.

Soterix Medical, Inc., doing business as Soterix Medical Technologies, manufactures and supplies transcranial electrical stimulation (tES), transcranial magnetic stimulation (TMS), and related neuromodulation medical devices to the federal government, operating as a prime contractor on federal research contracts and grants (96% of recent awards) with no named subcontractor relationship. The company, a for-profit manufacturer headquartered in Woodbridge, New Jersey, competes predominantly under Small Business Innovation Research (SBIR) set-asides and total-small-business set-asides, though a portion of recent purchase orders carry no set-aside designation.

Soterix Medical's federal footprint centers on two distinct capability streams. The first is hardware manufacture and delivery of custom waveform generators, EEG recorders, interferential stimulator systems, and high-definition transcranial electrical stimulation systems equipped with image-guided neuronavigation, customizable waveforms up to 128 independent stimulation channels, and frequency adjustment from 0.001 to 5,000 Hz. Representative purchase orders include a May 2026 VA small-business-set-aside order for an MxN-5/33 PRO HD-tES Custom Waveform Generator system with dual HDcap units ($40 thousand, Department of Veterans Affairs Veterans Integrated Service Network 22); a January 2025 sole-source purchase order from VA Veterans Integrated Service Network 21 for a Custom Waveform Generator ($31 thousand); and a September 2024 purchase order from the National Institute of Diabetes and Digestive and Kidney Diseases for non-invasive neuromodulation technologies ($25 thousand). The second stream is SBIR-funded research and development for advanced neuromodulation applications, including a $1.98 million DARPA SBIR Phase II contract (August 2021, exercising options through September 2023) for neurological stimulation systems, a $1.1 million Defense Health Agency SBIR Direct-to-Phase-II contract (September 2022) for an In-Flight Certified Device for Pain Relief called AeroRelief, an $849 thousand NASA SBIR Phase II contract (May 2022) for the Galvanic Induced Disorientation Simulation Trainer (GIST), and a $1 million Department of Education SBIR Phase II contract (May 2022) for educational neuroscience applications. Soterix Medical also holds a $100 thousand NASA SBIR Phase III matching-funds contract (April 2025) to advance GIST validation.

Customer concentration spans research and clinical agencies. By award count, the top customer pool covers 45% of recent awards: the National Institute on Drug Abuse (5 awards, $2 million combined potential value), NASA Shared Services Center (5 awards, $1.1 million), and three VA Veterans Integrated Service Networks (4 awards each, ranging from $39 thousand to $111 thousand). By dollar value, the distribution shifts — DARPA and the National Institute on Drug Abuse account for the majority of the $8.9 million in combined potential value, with the Defense Health Agency, the Department of Education, and NASA rounding out the top-dollar customers. Soterix Medical also acts as a sub-recipient on federal grants: it performs individualized current-flow modeling, manufactures hardware and software, and provides device training under a Mount Sinai-led grant (award date December 2025) and develops home-based transcranial direct-current stimulation (tDCS) and mindfulness interventions for cannabis use disorder under a New York University prime grant (award date September 2025).

Award volume declined from eight awards in 2021 to one in 2026, with two awards (combined potential value $890 thousand) reaching ultimate completion inside the next twenty-four months, creating modest recompete exposure. The vendor's NAICS footprint is primarily Analytical Laboratory Instrument Manufacturing (17 awards), with secondary categories in Research and Development in the Physical, Engineering, and Life Sciences (9 awards) and Electromedical and Electrotherapeutic Apparatus Manufacturing (4 awards). Service Contract Inventory data covering FY2024 show $385 thousand in SCI-reportable invoiced revenue across 1.3 FTEs on prime contracts, with government-paid rates at a flat median of $147.70 per hour. No subcontractors are named in the SCI dataset; Soterix Medical delivers its own technical and administrative labor. The company's grant work in depression treatment, addiction, and neuromodulation research forms a separate revenue stream outside the contract footprint.
