itemis AG vs Conclusive Engineering: overview
itemis AG
itemis AG was founded in 2003 in Lünen, Germany and has consolidated its headquarters in Dortmund since 2025, with a team of 220 people. The firm organizes its business around three defined areas: compliance engineering for safety-critical and connected products, model-based development tools, and custom enterprise applications, with functional safety consulting for ISO 26262 and IEC 61508 as a named, dedicated practice rather than a service tacked onto general firmware development. More than two decades of operating history in that specific compliance-engineering space gives it a track record a buyer can check against actual certified programs.
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 design-phase consulting service exists as a distinct offering from its full embedded systems build capability, covering microcontroller and FPGA-based architecture decisions before a client commits to hardware and firmware development, with listed partner status at Nordic Semiconductor and Texas Instruments backing chip-selection advisory. Automotive and healthcare clients requiring ISO 26262 and IEC 61508 alignment give the consulting practice regulated-industry credibility beyond a general embedded advisory pitch.
