One Stop Systems designs and manufactures ruggedized, high-performance computing systems for edge deployments — platforms that move or operate in harsh environments like aircraft, ships, submarines, land vehicles, and drones. OSS's core products include compute servers, GPU accelerator systems, high-density flash storage arrays, and PCIe switch fabric and expansion systems. Customers use these to run AI/ML inference, sensor fusion, autonomous navigation, and real-time situational awareness. The core value proposition is that standard datacenter servers can't survive rugged environments, while traditional military computers lack datacenter-class performance — OSS bridges that gap by packaging leading commercial components from NVIDIA, AMD, Intel, and others into compact, shock- and vibration-resistant systems. OSS sells primarily to defense prime contractors like Raytheon, Lockheed Martin, and L3Harris, as well as commercial OEMs in medical imaging and autonomous vehicles, who embed OSS hardware into their own products. OSS's business model moves customers through customer-funded development (lower margin, but establishes OSS as the incumbent), into low-rate and then full-rate production (higher margin), and finally sustainment. Key programs include the U.S. Navy's P-8 Poseidon maritime patrol aircraft, where OSS holds a sole-source supplier agreement with lifetime contracted revenue exceeding $65M. Following the sale of its German distribution subsidiary Bressner in December 2025, OSS is now a pure-play ruggedized AI compute provider, with a strengthened balance sheet and active interest in M&A to expand its platform capabilities.
