itemis AG vs RMB Consulting: overview
itemis AG
itemis AG was founded in 2003 in Lünen, Germany and has consolidated its headquarters in Dortmund since 2025, with a team of 220 people. The firm organizes its business around three defined areas: compliance engineering for safety-critical and connected products, model-based development tools, and custom enterprise applications, with functional safety consulting for ISO 26262 and IEC 61508 as a named, dedicated practice rather than a service tacked onto general firmware development. More than two decades of operating history in that specific compliance-engineering space gives it a track record a buyer can check against actual certified programs.
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. The firm covers hardware, software, and firmware consulting with a team of 1 to 10 people, positioning it at the smallest and most direct end of the advisory spectrum on this list. Nigel Jones is also a recognized voice in the embedded engineering community through long-running technical blogging on firmware design topics, which gives a prospective client a substantial public track record to evaluate before ever making contact.
