Barr Group vs exida: 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.
exida
exida was founded in 2000 and is headquartered in Sellersville, Pennsylvania. The company grew out of founder Dr. William Goble's relationship with TÜV Bayern during a product safety certification process and has since become one of the few product safety certification bodies in the world, providing consulting, certification, and lifecycle management for IEC 61508, IEC 61511, IEC 62443, and ISO 26262. Its ARCHx knowledge base embeds more than 30 years of accumulated hardware, software, FPGA, and cybersecurity design and analysis experience. For a firmware program that needs a certification body's opinion rather than just a consultant's opinion, exida is the more direct fit of any firm on this list.
