DE Design Works vs Sigma Design: overview
DE Design Works
DE Design Works was founded in 2002 and operates from Chesterfield, Missouri with a team in the 11 to 50 employee range. Its architecture advisory work centers on PCB and hardware design for rugged industrial, medical, and military applications alongside embedded software and firmware, including secure OTA update strategy and embedded Linux board support package architecture. For a buyer whose consulting need is specifically ruggedization or regulated-application architecture, this is a firm with a track record narrowly built around those exact constraints.
Sigma Design
Sigma Design (operating as SIGMADESIGN) was established in 1994 in Portland, Oregon and is now headquartered in Camas, Washington with approximately 283 employees across five continents. Its advisory scope covers mechanical design, industrial design, testing, and software and firmware engineering, positioning itself as a full product design and engineering partner rather than a firmware-only consultant. For an architecture review that needs to weigh industrial design, mechanical engineering, and firmware decisions together, Sigma Design's breadth and headcount give it more parallel-program capacity than most boutique advisory firms.
