Ripcord Designs vs Sigma Design: overview
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.
Sigma Design
Sigma Design (operating as SIGMADESIGN) was established in 1994 in Portland, Oregon and is now headquartered in Camas, Washington with approximately 283 employees across five continents. Its advisory scope covers mechanical design, industrial design, testing, and software and firmware engineering, positioning itself as a full product design and engineering partner rather than a firmware-only consultant. For an architecture review that needs to weigh industrial design, mechanical engineering, and firmware decisions together, Sigma Design's breadth and headcount give it more parallel-program capacity than most boutique advisory firms.
