STUMPWORX LLC

Stumpworx LLC specializes in the design, development, and intellectual property advancement of advanced prosthetic suspension systems, with a focus on transradial applications. Their core capabilities center on biomechanical engineering, human-machine interface optimization, and functional prototyping for upper-limb prosthetics. The company leverages physical and engineering sciences to refine suspension technologies that enhance comfort, stability, and user control—critical factors in mobility restoration for amputees. Their technical expertise includes material science selection, biomechanical modeling, ergonomic interface design, and iterative prototyping aligned with clinical feedback loops. A key differentiator is their targeted innovation in suspension system performance, addressing long-standing challenges in residual limb load distribution and dynamic fit without compromising wearability or ease of donning. Stumpworx LLC has demonstrated direct engagement with the Department of Veterans Affairs, delivering research and development solutions tailored to veteran-specific rehabilitation needs. Their work with VA centers on improving functional outcomes for service-related amputees through evidence-based prosthetic design, suggesting a mission-aligned partnership focused on veteran-centric innovation and clinical translation. The contractor’s primary industry focus is in research and development within the physical and engineering sciences, specifically applied to medical device innovation. This places them at the intersection of biomedical engineering and assistive technology, serving a niche but critical segment of the defense and veteran healthcare markets. Their market positioning is that of a specialized R&D provider, advancing proprietary solutions for prosthetic interface challenges rather than mass manufacturing. Stumpworx LLC is a Service-Disabled Veteran-Owned Small Business operating from Portland, Oregon. Their 2J entity structure reflects a small, agile organizational model optimized for responsive, mission-driven engineering projects. The SDVOSB certification underscores their commitment to veteran empowerment and aligns their capabilities with federal procurement priorities focused on veteran-owned innovation.
