Simx, Inc.

Simx, Inc., a San Jose, California-based small business, delivers immersive virtual reality medical simulation software, training platforms, and VR headsets to the Department of Defense and federal healthcare agencies as a prime contractor on 87 of its 88 recent awards, competing predominantly in the Department of the Air Force's SBIR and STTR research portfolios under total small business set-asides.

Simx specializes in scenario-based VR training for combat casualty care, aeromedical evacuation, surgical education, trauma management, CBRNE response, and emergency medical response across military medical personnel. The company's flagship platform, SimX Valor Virtual Reality Medical Simulation System (VRMSS), delivers headset-based immersive training environments where medical professionals practice complex procedures and trauma protocols in risk-free settings. Recent representative prime awards include a $1.8 million Air Force Research Laboratory SBIR Phase II contract for end-user scenario authoring and configuration (awarded May 2023), a $1.7 million AFRL SBIR Phase II contract for a virtual reality medical simulation system serving Air Force Special Operations Command and Air Combat Command (June 2022), and a $1.25 million Air Force Research Laboratory STTR Phase II contract for surgical perioperative expeditionary medical support training for Air Force nursing personnel (July 2024). The company also executes lower-value operational delivery orders from active medical groups across Air Mobility Command, Air Education and Training Command, Air Forces Europe and Africa, and the Defense Health Agency, covering hardware procurement (HTC Vive Focus 3 headsets, Dell moderator laptops), software licensing, scenario packages, and integration support.

Customer concentration sits heavily with the Air Force research and operational commands. The Department of the Air Force Materiel Command Research Laboratory anchors 33 awards worth $22.2 million combined potential value — 78% of all dollars in the recent footprint — reflecting Simx's deep positioning in SBIR and STTR Phase II and Phase III awards. Air Mobility Command (11 awards, $1 million), the broader Department of the Air Force (6 awards, $1.2 million), Air Forces Europe and Africa (6 awards, $254 thousand), and Air Force Special Operations Command (5 awards, $1.1 million) together account for 28 additional awards. Non-Air Force customer bases include the Defense Health Agency (4 awards, $519 thousand), Veterans Integrated Service Network 10 and 20 (combined 5 awards), U.S. Customs and Border Protection (1 award, $420 thousand), the Army Research, Development and Engineering Command (1 award, $96 thousand), and the Secret Service (1 award, $185 thousand), representing 20 distinct customer agencies overall.

Simx sits on no named government-wide contract vehicles or GWACs; its work flows through direct SBIR/STTR awards, sole-source and FAR 6.302-1 authority (limited competition) purchase orders from operational medical groups, and a single identified sub relationship as a sub-award under Alutiiq Information Management, LLC on a Navy reverse-engineering and laboratory engineering services contract (awarded February 2026). Award activity has declined: 19 awards in 2022, 25 in 2023, 14 in 2024, 10 in 2025, and 3 to date in 2026. Eight awards with ultimate completion dates in the next twenty-four months carry a combined potential value of $5.1 million — a recompete exposure concentrated in SBIR/STTR Phase II and Phase III awards that will cycle off or require renewal through new solicitations.

The vendor is a child entity within Madison Healthcare Holdings LLC, a for-profit corporate parent. Simx's award portfolio splits across NAICS 541712 (Research and Development in Physical, Engineering, and Life Sciences) for 34 awards and NAICS 511210 (Software Publishers) for 11 awards, with remaining work classified under Educational Support Services and Audio/Video Equipment Manufacturing. PSC codes reflect the same split: National Defense R&D Services and Applied Research (30 awards), Training Aids (13 awards), and application development software (11 awards combined). Across 88 awards, $27.3 million has been obligated (96% of combined potential value), indicating mature contract execution against the research footprint. The vendor competes entirely within small business set-asides and does not hold seats on open, full-and-open federal contract vehicles; its federal business model depends on continued SBIR/STTR program eligibility and sole-source authority for established medical group customers.
