Conclusive Engineering vs Zone7 Engineering: overview
Conclusive Engineering
Conclusive Engineering was founded in 2018 in Katowice, Poland by Jakub Klama and Wojciech Kloska, with a team most sources place between 30 and 50 engineers. Its scope covers embedded systems design and manufacturing support, spanning microcontroller and FPGA-based firmware alongside in-house hardware design and PCB development, with automotive and healthcare clients where ISO 26262 and IEC 61508 alignment factor into vendor selection. Listed partner status with Nordic Semiconductor and Texas Instruments gives a procurement evaluator a documented, third-party-verifiable credential rather than a self-reported 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.

Conclusive Engineering vs Zone7 Engineering: pros and cons
| Conclusive Engineering | |
|---|---|
| + | Nordic Semiconductor and Texas Instruments partner status is verifiable in each vendor's own public directory, useful for an RFP vendor-qualification step |
| + | In-house PCB development means a hardware+firmware line item can be scoped to one vendor instead of two |
| + | ISO 26262 and IEC 61508 alignment work suits safety-relevant automotive and industrial procurement requirements |
| + | FreeBSD depth is uncommon among competing bidders, most of whom default to Linux or bare-metal only |
| - | Team size estimates vary between roughly 30 and 50 engineers depending on source, worth confirming directly for a large program's bench-depth requirement |
| - | 7 years of operating history is shorter than several larger competitors an RFP evaluation might weigh for track record |
| - | No published pricing or minimum engagement threshold |
| 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 |
