Conclusive Engineering vs Integra Sources: 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.

Integra Sources

Integra Sources was founded in 2014 and is headquartered in Astana, Kazakhstan, with a team reported between roughly 24 and 51 employees across Asia, North America, and Europe. The company's scope covers electronic device design, firmware and software development, and full-cycle engineering from PCB and FPGA design through robotics and connected-product monitoring systems, with more than 250 completed projects for over 100 clients across Europe, the USA, Australia, and Asia cited as its delivery track record. For an RFP evaluating project-volume evidence, that 250-project figure is a specific, referenceable claim.

Conclusive Engineering vs Integra Sources: 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
Integra Sources
+ More than 250 completed projects across four continents is a specific, checkable delivery-volume claim
+ Full-cycle scope from PCB and FPGA design through firmware and connected-product monitoring reduces vendor coordination
+ 11 years of operating history with a client base spanning Europe, the USA, Australia, and Asia
+ Robotics engineering experience is a specific capability not every embedded firmware vendor lists
- Reported team size varies between roughly 24 and 51 across sources, worth confirming for large concurrent RFP capacity needs
- No published pricing or minimum engagement figure
- Its Kazakhstan headquarters may raise timezone or in-person coordination questions for some North American or European RFPs
