RMB Consulting vs Zone7 Engineering: overview

RMB Consulting

RMB Consulting has operated in embedded systems design and consulting since 1995, run by founder and chief engineer Nigel Jones, who brings more than 30 years of professional embedded systems engineering experience and a long-running record of public technical writing on firmware design. For a client hiring a small team, working directly with a single named, 30-year-tenured engineer, rather than being assigned whichever staff member is available, is close to the smallest and most direct version of an engineering-hire relationship this list offers.

Zone7 Engineering

Zone7 Engineering is a Portland, Oregon electronics engineering practice founded and run by David Ashman, a senior electronics engineer with extensive experience designing digital and analog circuitry around various microprocessors and DSPs alongside embedded C/C++ firmware development. For a client evaluating the smallest possible version of an engineering-hire relationship, this is a firm where the person quoting the project, designing the architecture, and writing the firmware are the same single named individual.

RMB Consulting vs Zone7 Engineering: pros and cons

RMB Consulting
+ 30 years of professional embedded engineering experience concentrated in one named, publicly verifiable principal
+ A substantial public technical writing record lets a hiring buyer evaluate expertise before ever making contact
+ 30 years of operating history under the same founder gives continuity most larger firms can't offer
+ Team size of 1 to 10 means zero layers between the client and the engineer doing the work
- A team of 1 to 10 people severely limits capacity for a large or multi-workstream engagement
- No published pricing or minimum engagement figure
- Availability may be constrained given the founder-led, low-headcount structure
Zone7 Engineering
+ Founder-led model means the person quoting a project is the same person who designs and builds it, with no account-management layer
+ Covers project planning through PCB design, firmware, prototyping, and production readiness in one continuous process
+ Analog and digital circuit design experience alongside firmware covers mixed-signal product requirements
+ 15 years of practice predates many boutique competitors on this list
- Solo or near-solo team size severely limits capacity for a project requiring multiple concurrent workstreams
- Public case study detail and named client references are very limited
- No published pricing or minimum engagement figure
