DE Design Works vs ARi: overview
DE Design Works
DE Design Works was founded in 2002 and is based in Chesterfield, Missouri, with a team in the 11 to 50 employee range. The firm pairs custom PCB hardware design with embedded firmware development for industrial, medical, and military clients, which reduces handoff friction on projects where hardware and firmware need to be co-designed rather than contracted separately. Public case studies and named clients are limited, so most specific claims beyond the company's core services rely on its own materials.
ARi
ARi traces its engineering roots to 2001 and began operating under the ARi brand in 2006, headquartered in East Peoria, Illinois, with seven additional locations across North America and Asia Pacific; the company reports more than 1,100 employees. Embedded software and firmware sit inside a much broader industrial engineering business that also covers mechanical product design, manufacturing engineering, industrial automation, and robotics, so ARi suits a client whose project spans hardware, firmware, and manufacturing rather than firmware in isolation. Its scale supports large industrial programs that a boutique firmware firm could not staff alone.

|---|---|
| + | More than 1,100 employees and eight total locations support very large industrial programs |
| + | Embedded firmware sits alongside mechanical design and manufacturing engineering for hardware-heavy products |
| + | Long engineering history predating the current brand, formalized under the ARi name in 2006 |
| - | Firmware is a smaller specialty inside a much larger industrial automation and manufacturing business |
| - | Scale and process overhead can be more than a small firmware-only project actually needs |
