Promenade Software vs Sigma Design: overview
Promenade Software
Promenade Software was founded in 2013 and is headquartered in Irvine, California with a small team, most recently reported around 11 employees. The firm's advisory value centers on applying web-framework development speed to embedded medical device software while holding to FDA-relevant safety-critical requirements, a specific architectural tension most general firmware consultants haven't solved for. Its CyberMed·Cloud product line adds a dedicated medical device cybersecurity advisory angle beyond general architecture consulting.
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.
