Conclusive Engineering vs Promwad: 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.

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.

Conclusive Engineering vs Promwad: 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
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
