Promenade Software vs RCM Technologies: 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.
RCM Technologies
RCM Technologies was founded in 1971 and is headquartered in Pennsauken, New Jersey, with 4,930 total employees across its full business. Its Aerospace & Defense division brings over 50 years of product lifecycle engineering experience, with embedded systems work covering mission and safety-critical software development, verification and validation up to DAL-A standards, and manufacturing and supply chain engineering. For a defense or aerospace RFP requiring DAL-A verification and validation experience, that specific certification level narrows the field of qualified bidders considerably.
