Barr Group vs EES: 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.

EES

Embedded Engineering Solutions (EES) was launched in 2012 and is based in Tempe, Arizona, with reported headcount varying across sources from roughly 3 to 50 employees, most consistently described as a small, senior-led firm. The company specializes in contract firmware, embedded systems, and hardware design engineering for the industrial sector, and its own positioning leans on being senior-led rather than layered with junior staff. For a hiring buyer specifically avoiding a large delivery organization, that's the stated value proposition, not an incidental trait.

Barr Group vs EES: pros and cons

Barr Group
+ Michael Barr's public technical writing and books give a prospective client a way to evaluate the team's judgment before ever making contact
+ Training as a core business line means the firm's engineers are practiced at explaining their reasoning, not just doing the work silently
+ 13 years of operating history built specifically around expert technical judgment rather than headcount growth
+ 51 to 200 employees give real bench depth for a firm this specialized
- Volume firmware development capacity is not the firm's stated focus, so a large parallel build program may need a second team
- No published consulting rate or minimum engagement figure
- Expert-witness work is a distinct practice from product engineering; confirm which team a specific inquiry reaches
EES

+ 13 years of operating history as a contract engineering firm for the industrial sector
+ Combines firmware, embedded systems, and hardware design in one team, covering multiple disciplines without separate specialist hires
+ Small size means a client's engagement represents a meaningful share of the firm's total capacity
- Reported employee counts vary widely across sources, from roughly 3 to 50, worth confirming current headcount directly
- Small team size caps capacity for a large or multi-workstream program
- No published pricing or minimum engagement figure
