Sigma Design vs A-listware: 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.
A-listware
A-listware was founded in 2017 and is headquartered in London, UK, with an R&D center in Ukraine and a reported 51 to 200 employees. The company's core model centers on delivering remote engineering teams to clients, with embedded systems and IoT advisory, including firmware architecture guidance, legacy system modernization, and hardware integration, named among its service lines. For an advisory engagement structured as staff augmentation rather than a fixed-deliverable consulting contract, A-listware's remote-team model is built specifically for that engagement shape.
