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 stated scope covers mechanical design and engineering, industrial design, testing, onsite contracting, and software and firmware engineering, positioning itself as a full product design and engineering partner rather than a firmware-only vendor. For an RFP that groups industrial design, mechanical engineering, and firmware into one deliverable, Sigma Design's breadth and headcount give it more parallel-program capacity than most boutique bidders on this list.
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 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 rather than firmware as a standalone bid item. That breadth suits an RFP where firmware is one line among controls, robotics, and systems integration rather than the entire scope.
