Sigma Design vs Integra Sources: 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.
Integra Sources
Integra Sources was founded in 2014 and is headquartered in Astana, Kazakhstan, with a team reported between roughly 24 and 51 employees across Asia, North America, and Europe. The company's advisory scope covers electronic device design, firmware and software architecture, and full-cycle engineering from PCB and FPGA design through robotics and connected-product monitoring systems, with more than 250 completed projects for over 100 clients across Europe, the USA, Australia, and Asia cited as its track record.
