Company profile
researched Aug 2026Xenex Disinfection Services Inc. develops and sells ultraviolet whole-room microbial reduction systems for healthcare facilities. Its core product line is the LightStrike family of "Germ-Zapping" robots, built on a patented pulsed xenon UV system, which the company states is the first and only FDA-authorized broad spectrum UV robot for whole room microbial reduction. Xenex reports that treatment deactivates at least 99% of pathogens on treated surfaces, citing figures for organisms including Acinetobacter baumannii, Clostridioides difficile, MRSA and Enterobacter cloacae, with cycle times as fast as two minutes for vegetative bacteria.
Beyond the devices, Xenex positions its offering as a program rather than a standalone purchase, bundling training, advanced workflow consulting intended to speed room turnover and improve throughput, and data support for facility quality programs. Its catalog spans LightStrike+ and LightStrike6 robots, the earlier LightStrike PXUV4, a handheld LED unit branded Deactivate, the TrackMate digital tracking system, and Xtra Care service plans. The company emphasizes evidence-based claims and collaboration with clinicians and scientific experts, and it maintains customer success materials featuring infection preventionists, quality directors and clinicians.
Founding story
Co-founders Mark (Tuck) Stibich and Julie Stachowiak, both epidemiologists, met while pursuing doctoral studies at Johns Hopkins University and shared an interest in research and public health impact. Seeking to give healthcare facilities a more effective way to prevent pathogen transmission, and to ensure that scientific evidence underpinned all company claims, they co-founded Xenex in 2008.
Business model
Xenex sells and supports UV microbial reduction hardware for healthcare and other facilities, pairing the LightStrike robots with service and support offerings such as staff training, workflow consulting, data support, and Xtra Care service plans. Complementary products include a handheld LED unit (Deactivate) and TrackMate, a digital tracking system, and the company offers government procurement options and account programs.
Revenue comes from sales of UV disinfection devices and related products together with attached services, including Xtra Care service plans, training and workflow consulting, and digital tracking via TrackMate.
