Barr Group vs Sigma Design: overview
Barr Group
Barr Group was founded in 2012 and is headquartered in Gaithersburg, Maryland, with a team in the 51 to 200 employee range. Led by CTO Michael Barr, a former editor-in-chief of Embedded Systems Design magazine and author of multiple embedded software books, the firm's identity centers on independent training, firmware process and architecture consulting, and legal and corporate technical expert-witness work rather than volume development. That positioning, expertise as the product rather than headcount as the product, is what a consulting-first buyer is specifically looking for when the engagement is advisory rather than build-and-ship.
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.
