Sigma Design vs Enginuity Inc.: overview
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.
Enginuity Inc.
Enginuity Inc. was founded in Halifax, Nova Scotia in 2003 and has grown to roughly 156 employees serving aerospace, defence, marine, and advanced manufacturing clients across Canada, the United States, and international markets. Its embedded and real-time firmware advisory capability sits alongside PCB design, industrial automation and controls, robotics integration, SCADA and HMI development, and PLC programming, reflecting a firm built around full-program industrial and defence engineering advisory rather than firmware architecture as a standalone offering.
