COMPANY 91 LLC

COMPANY 91 LLC specializes in the design, integration, and testing of precision measuring and controlling devices for defense applications, with a demonstrated focus on nuclear, biological, and chemical (NBC) system test infrastructure. Their core capability centers on developing specialized test stands that validate the performance, calibration, and operational readiness of NBC detection and monitoring components under controlled environmental conditions. This requires deep expertise in sensor interface engineering, data acquisition systems, embedded control firmware, and ruggedized hardware integration compliant with military environmental and electromagnetic standards. The company’s technical differentiation lies in its ability to deliver turnkey test platforms that bridge laboratory-grade instrumentation with field-deployable system validation requirements, ensuring traceable metrology and repeatability critical to defense readiness. The contractor has established a direct working relationship with the Department of Defense, delivering mission-critical test equipment tailored to NBC defense programs. Their engagement reflects a niche specialization in supporting defense logistics and readiness systems, particularly in the validation of sensor-based detection and response technologies used across Army, Navy, and joint force units. Operating under NAICS 334519, COMPANY 91 LLC is positioned within the niche segment of custom measuring and controlling device manufacturing, serving defense and national security verticals that require non-standard, low-volume, high-integrity instrumentation. Their market positioning is that of a specialized systems integrator focused on defense-specific test and validation environments rather than mass-produced commercial devices. As a small business structured as 2K, COMPANY 91 LLC operates from Madison, Wisconsin, with no federal certifications on record. The company’s footprint reflects a lean, technically focused entity capable of delivering bespoke engineering solutions with agility, catering to defense customers requiring rapid prototyping and validation of specialized test systems.
