exida vs Ripcord Designs: 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.

Ripcord Designs

Ripcord Designs is a UK-based electronic and embedded software design consultancy operating from the London and Cambridge area, founded around 2015 by Adam, previously Engineering Director at Broadcast Sports. The firm explicitly positions its advisory role as providing an independent perspective on a client's product, architecture, and technical risks, spanning MedTech, IVD and lab devices, robotics and industrial, and consumer electronics sectors, before or alongside hands-on electronics design, embedded software development, and compliance support work.
