itemis AG vs A2e Technologies: 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.
A2e Technologies
A2e Technologies was founded in 2004 and is headquartered in San Diego, California with a team reported between 11 and 50 engineers, commonly cited around 47. Beyond hands-on hardware, FPGA, and firmware development, the firm's anti-tamper hardware security design work functions as a specialized advisory practice for defense and space clients navigating threat-model and export-control requirements, under ITAR certification. For a buyer whose consulting need is specifically security-architecture advisory in a regulated defense context, that ITAR-certified anti-tamper specialty is difficult to find outside a handful of firms.
