exida vs Promenade Software: 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.
Promenade Software
Promenade Software was founded in 2013 and is headquartered in Irvine, California with a small team, most recently reported around 11 employees. The firm's advisory value centers on applying web-framework development speed to embedded medical device software while holding to FDA-relevant safety-critical requirements, a specific architectural tension most general firmware consultants haven't solved for. Its CyberMed·Cloud product line adds a dedicated medical device cybersecurity advisory angle beyond general architecture consulting.
