One Stop Systems Inc (NASDAQ: OSS) is a hardware technology company that designs and manufactures ruggedized edge computing systems, including high-performance servers, flash-based storage, and PCIe switch fabric products for deployment in harsh physical environments. Revenue comes from transactional hardware sales to both commercial and military customers who need datacenter-class compute performance at the edge, outside controlled data center conditions. OSS serves defense and commercial end markets where standard off-the-shelf servers cannot survive operational conditions such as extreme temperature, vibration, shock, moisture, and unstable power. The company competes on PCIe expertise, ruggedized design, and custom BIOS engineering. Products incorporate components from NVIDIA, AMD, and Intel. In FY2025, the company raised $12.5 million gross through a registered direct offering of 2.5 million common shares, closed October 1, 2025. OSS is headquartered in the United States. Michael Knowles serves as a senior executive, as indicated by the FY2025 10-K filed March 18, 2026.
