Promenade Software vs Integra Sources: 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.

Integra Sources

Integra Sources was founded in 2014 and is headquartered in Astana, Kazakhstan, with a team reported between roughly 24 and 51 employees across Asia, North America, and Europe. The company's scope covers electronic device design, firmware and software development, and full-cycle engineering from PCB and FPGA design through robotics and connected-product monitoring systems, with more than 250 completed projects for over 100 clients across Europe, the USA, Australia, and Asia cited as its delivery track record. For an RFP evaluating project-volume evidence, that 250-project figure is a specific, referenceable claim.

Promenade Software vs Integra Sources: pros and cons

Promenade Software
+ Development approach specifically targets faster iteration within FDA-relevant safety-critical constraints, a stated differentiator against slower-moving medical firmware vendors
+ CyberMed·Cloud product line signals dedicated medical device cybersecurity expertise beyond general firmware work
+ 12 years of operating history focused entirely on medical device software
+ Small team size gives an RFP evaluator direct access to senior engineers during technical evaluation
- Around 11 employees is a small bench for an RFP requiring multiple concurrent medical device programs
- Sole medical-device focus is a narrower fit for an RFP spanning non-medical hardware categories
- No published pricing or minimum engagement figure
Integra Sources
+ More than 250 completed projects across four continents is a specific, checkable delivery-volume claim
+ Full-cycle scope from PCB and FPGA design through firmware and connected-product monitoring reduces vendor coordination
+ 11 years of operating history with a client base spanning Europe, the USA, Australia, and Asia
+ Robotics engineering experience is a specific capability not every embedded firmware vendor lists
- Reported team size varies between roughly 24 and 51 across sources, worth confirming for large concurrent RFP capacity needs
- No published pricing or minimum engagement figure
- Its Kazakhstan headquarters may raise timezone or in-person coordination questions for some North American or European RFPs
