itemis AG vs DE Design Works: overview
itemis AG
itemis AG was founded in 2003 in Lünen, Germany and has consolidated its headquarters in Dortmund since 2025, with a team of 220 people. The firm organizes its business around three defined areas: compliance engineering for safety-critical and connected products, model-based development tools, and custom enterprise applications, with functional safety consulting for ISO 26262 and IEC 61508 as a named, dedicated practice rather than a service tacked onto general firmware development. More than two decades of operating history in that specific compliance-engineering space gives it a track record a buyer can check against actual certified programs.
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.
