Barr Group vs Oxalis 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 training, firmware process and architecture work, and legal technical expert-witness services rather than volume staffing. For an engineering leader deciding who to bring onto a team, working alongside people whose technical writing they've likely already read is a different kind of hiring signal than a generic vendor profile.
Oxalis Design
Oxalis Design is a Bristol, UK electronics and embedded systems consultancy founded by Alex Turner and Alex Thornicroft, both experienced electronics and software engineers who remain personally involved in client work rather than having moved fully into management. For a client evaluating team fit at the smallest scale, this means the people making architecture decisions are the same people who will be reachable throughout the engagement, not a sales contact who hands the work to unnamed staff.
