exida vs WebbyLab: 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.

WebbyLab

WebbyLab was founded in 2011 by Anton Morozov and Viktor Turskyi and operates from Kyiv and London with more than 120 engineers across hardware, firmware, and software disciplines. The firm's full-cycle framing means architecture advisory runs from hardware selection through firmware and the cloud or mobile application layer, with IoT and embedded systems named as a core specialty and Fortune 500 clients cited among its customer base. That framing fits a buyer whose consulting question spans the whole connected-device stack, not firmware in isolation.
