Integra Sources vs Zone7 Engineering: overview
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.
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.
