itemis AG vs Doulos: 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.
Doulos
Doulos was founded in 1990 and is headquartered in Ringwood, Hampshire, UK, with a North American base in Silicon Valley and a team reported between 11 and 200 employees depending on source. In 2022, the founders transferred ownership to the staff through an Employee Ownership Trust, and the firm has set what it describes as the industry standard for training and know-how across system-on-chip, embedded software and security, and AI and deep learning for more than three decades. For a buyer evaluating consulting relationships on longevity and independence from outside investors, the employee-ownership structure is a specific, verifiable signal.
