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 built its practice specifically to accelerate embedded medical device software development while holding to FDA-relevant safety-critical requirements, applying web-framework concepts to a domain that traditionally moves slower. Regulatory-compliance certifications and a CyberMed·Cloud product line targeted at medical device security give it a specific credential set relevant to a medical device RFP beyond general firmware capability.
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.
