DE Design Works vs Sigma Software Group: overview
DE Design Works
DE Design Works was founded in 2002 and operates out of Chesterfield, Missouri with a team in the 11 to 50 employee range. Embedded software and firmware design has been a core service since the company's founding rather than an addition to a broader product-design practice, spanning bootloaders, secure OTA update signing and rollback, and embedded Linux board support package bring-up. The firm also does electronics engineering, PCB design, and prototyping, so a client can source firmware and the surrounding hardware from the same team.
Sigma Software Group
Sigma Software Group was founded in Kharkiv, Ukraine in 2002 by five friends and now employs more than 1,100 people across Ukraine, Sweden, Poland, and the United States. In 2006 the Swedish IT conglomerate Sigma Group acquired a 60% stake in the company, an ownership structure that has held since; the remaining 40% stays with the original Ukrainian founders. Its embedded and IoT services cover application development, firmware, middleware, device drivers, and human-machine interfaces, delivered as one practice within a much larger portfolio spanning gaming, aviation, and telecom software.
