Pillar Analysis
Strategic Assessment
Strategic Vector
StemRad is pursuing a dual-use radiation-protection strategy spanning spaceflight, defense, nuclear emergency response, and first-responder markets, with AstroRad validation through Artemis I and 360 Gamma adoption by the U.S. National Guard. Its strategic position is strengthened by NASA, Lockheed Martin, DLR, and Israeli space-sector relationships, but public evidence of recent commercial scale and organizational expansion remains limited.
Efficiency Ratio
The company appears resource-efficient, converting a small reported workforce of 11–50 employees into high-value aerospace validation and defense procurement, although limited public revenue and delivery data prevent precise assessment.
Evidence Signals
Research and project reporting stated that AstroRad significantly reduced radiation exposure to critical organs during major solar particle events, based on Artemis I data.
Background · older than 12 months
StemRad announced a $4.4 million contract with the National Guard Bureau for its 360 Gamma selective-shielding technology.
AstroRad completed the Artemis I lunar mission, with dosimeter data indicating approximately 60% reduction in radiation exposure from solar particle events.
A Redwire-led project with StemRad successfully manufactured an AstroRad vest subunit aboard the International Space Station using low-density polyethylene, supported by Space Florida and the Israel Innovation Authority.
StemRad’s technology was selected for the Jerusalem Post’s Top 10 Israeli Inventions of the Decade.
NASA, the German Aerospace Center, and the Israel Space Agency signed an agreement to fly StemRad’s AstroRad vest on NASA’s Artemis I mission.
StemRad completed a $6.5 million Series C round, bringing disclosed private funding without grants to $12 million.
- About
- Manufactures personal protective equipment designed to selectively shield bone marrow from gamma radiation. The product line includes the 360 Gamma belt for first responders and the AstroRad vest for deep-space astronaut protection, utilizing ergonomic designs to maximize survival without restricting mobility.
- Relevancy
- Provides critical radiation protection for military personnel in nuclear environments and space operations. AstroRad vest protects astronauts during deep space missions, while 360 Gamma enables first responders to operate in radiological emergencies. Essential for nuclear incident response and space-based military operations.
