Promwad vs Zone7 Engineering: overview
Promwad
Promwad was founded in 2004 by Roman Pakholkov and is headquartered in Essen, Germany with roughly 146 employees across Europe, North America, and Asia. Its engagement scope bundles embedded software development, hardware design, PCB layout, and enclosure design, with ASIL-C functional-safety work in automotive infotainment and ECU development alongside telecom, digital TV, and industrial automation programs. For an automotive or safety-relevant RFP, ASIL-C is a specific, checkable credential rather than a general safety claim.
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. Its stated scope covers project planning, PCB and circuit design, embedded firmware development, prototyping, and production-readiness support. For an RFP scoped small enough for a solo or near-solo practitioner, that direct-founder-involvement model removes account-management layers entirely, though it also caps how much concurrent capacity is available.

Promwad vs Zone7 Engineering: pros and cons
| Promwad | |
|---|---|
| + | ASIL-C functional-safety credential in automotive ECU and infotainment work is independently checkable against automotive safety standards |
| + | Electronics design, PCB layout, and firmware sit inside one company, reducing coordination risk on a multi-line-item RFP |
| + | 21 years of operating history and roughly 146 people give more delivery capacity than most boutique competing bidders |
| + | Industry spread across telecom, automotive, digital TV, and industrial automation reduces single-sector concentration risk for a diversified buyer |
| - | ASIL-C is one level below the ASIL D some automotive safety RFPs require, worth confirming fit before shortlisting |
| - | 146 employees spread across several industries means firmware specialists are shared across a broader practice, not a dedicated firmware-only bench |
| - | No published pricing or minimum engagement figure |
| Zone7 Engineering | |
|---|---|
| + | Founder-led model means direct senior electronics engineering involvement on every engagement, 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 |
| + | Founding year (2010) predates many boutique competitors, giving over a decade of practice |
| - | Solo or near-solo team size severely limits capacity for an RFP requiring multiple concurrent workstreams |
| - | Public case study detail and named client references are very limited |
| - | No published pricing or minimum engagement figure |
