Promwad vs Integra Sources: 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.

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.

Promwad vs Integra Sources: 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
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
