XTREMIS, INC.

XTREMIS, INC. specializes in advanced research and development for physical, engineering, and life sciences systems, with a demonstrated focus on virtualized environments for spectrum experimentation and research. The company delivers high-fidelity simulation platforms that enable dynamic radio frequency testing, signal analysis, and electromagnetic environment modeling—critical for defense communications, electronic warfare, and spectrum dominance initiatives. Their technical expertise includes software-defined radio architectures, real-time signal processing, networked testbeds, and secure virtual infrastructure for spectrum agility experiments. XTREMIS differentiates itself through its ability to design and deploy reconfigurable, scalable virtual environments that replicate complex operational spectra, supporting rapid prototyping and validation of next-generation radio systems without physical hardware constraints. The contractor has delivered solutions for the Department of Defense, specifically supporting advanced spectrum research initiatives under BAA solicitations. Their work aligns with DoD priorities in electromagnetic spectrum superiority, including counter-Jamming, spectrum sharing, and cognitive radio technologies. The relationship reflects a targeted engagement in experimental defense R&D, suggesting a niche role in supporting DARPA, AFRL, or Army C5ISR Center efforts focused on next-generation RF systems. XTREMIS operates primarily within NAICS 541715, which encompasses applied scientific research for defense and aerospace applications. Their market positioning centers on enabling experimental infrastructure for electromagnetic systems, serving defense technology development markets that require validated, repeatable, and secure virtual testbeds. They are not focused on biotechnology or nanotechnology but on the engineering and physical science domains underpinning modern communications and sensing systems. As a small business structured as a 2L entity based in Washington, D.C., XTREMIS maintains a lean, mission-driven profile with no public certifications. Its geographic proximity to federal R&D hubs supports direct collaboration with defense science and engineering stakeholders, positioning it as a specialized contractor in the national security technology ecosystem.
