Doulos vs Promwad: overview
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.
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 advisory work bundles embedded software architecture, hardware design, and PCB layout guidance, with ASIL-C functional-safety experience in automotive infotainment and ECU development alongside telecom, digital TV, and industrial automation consulting. For an automotive or safety-relevant architecture review, ASIL-C is a checkable credential rather than a general safety claim.
