exida vs Integra Sources: 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.
Integra Sources
Integra Sources was founded in 2014 and is headquartered in Astana, Kazakhstan, with a team reported between roughly 24 and 51 employees across Asia, North America, and Europe. The company's advisory scope covers electronic device design, firmware and software architecture, and full-cycle engineering from PCB and FPGA design through robotics and connected-product monitoring systems, with more than 250 completed projects for over 100 clients across Europe, the USA, Australia, and Asia cited as its track record.
