exida vs Promwad: overview
exida
exida was founded in 2000 and is headquartered in Sellersville, Pennsylvania. The company grew out of founder Dr. William Goble's relationship with TÜV Bayern during a product safety certification process and has since become one of the few product safety certification bodies in the world, providing consulting, certification, and lifecycle management for IEC 61508, IEC 61511, IEC 62443, and ISO 26262. Its ARCHx knowledge base embeds more than 30 years of accumulated hardware, software, FPGA, and cybersecurity design and analysis experience. For a firmware program that needs a certification body's opinion rather than just a consultant's opinion, exida is the more direct fit of any firm on this list.
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.
