RMB Consulting vs Integra Sources: pros and cons

RMB Consulting
+ 30 years of professional embedded systems experience concentrated in a single named principal, not diluted across a large team
+ 30 years of operating history under the same founder gives long continuity of technical judgment
+ A substantial public record of technical writing on firmware design topics lets a prospective client evaluate expertise before engaging
+ Very small team size means no account-management layer 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
Integra Sources
+ More than 250 completed projects across four continents is a specific, checkable advisory-volume claim
+ Full-cycle scope from PCB and FPGA design through firmware advisory reduces vendor coordination
+ 11 years of operating history with a client base spanning Europe, the USA, Australia, and Asia
+ Robotics engineering advisory experience is a specific capability not every embedded consultancy lists
- Reported team size varies between roughly 24 and 51 across sources, worth confirming for a large concurrent advisory engagement
- No published pricing or minimum engagement figure
- Its Kazakhstan headquarters may raise timezone or in-person coordination questions for some North American or European advisory relationships
