USA Firmware vs Integra Sources: overview
USA Firmware
USA Firmware was founded in 2011 by Bob Scaccia and operates from Brecksville, Ohio with a team of around 17 people. Its managed design services bundle electrical engineering, firmware, FPGA design, embedded software, and Linux expertise into a single discovery-through-production-enablement process, positioned for buyers who want one accountable vendor rather than coordinating separate electrical, firmware, and FPGA contractors on an RFP. Leadership brings a stated 150-plus combined years of experience concentrated in a small, senior team.
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.

| 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 |
