RMB Consulting vs Oxalis Design: 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.

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.

+ Focus on electronics and embedded firmware exclusively, without a broader IT practice diluting attention
+ RF design capability in-house means wireless connectivity work doesn't require a separate specialist

- A team of 2 to 10 people limits capacity to a small number of concurrent client programs at any time
- Publicly verifiable founding date and detailed case study history are limited
- No published pricing or minimum engagement figure
