Promenade Software vs Zone7 Engineering: 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.
Zone7 Engineering
Zone7 Engineering is a Portland, Oregon electronics engineering practice founded and run by David Ashman, a senior electronics engineer with extensive experience designing digital and analog circuitry around various microprocessors and DSPs alongside embedded C/C++ firmware development. Its stated scope covers project planning, PCB and circuit design, embedded firmware development, prototyping, and production-readiness support. For an RFP scoped small enough for a solo or near-solo practitioner, that direct-founder-involvement model removes account-management layers entirely, though it also caps how much concurrent capacity is available.
