itemis AG vs USA Firmware: overview
itemis AG
itemis AG was founded in 2003 in Lünen, Germany and has consolidated its headquarters in Dortmund since 2025, with a team of 220 people. The firm organizes its business around three defined areas: compliance engineering for safety-critical and connected products, model-based development tools, and custom enterprise applications, with functional safety consulting for ISO 26262 and IEC 61508 as a named, dedicated practice rather than a service tacked onto general firmware development. More than two decades of operating history in that specific compliance-engineering space gives it a track record a buyer can check against actual certified programs.
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 advisory into a single discovery-through-production-enablement process, positioned for buyers who want one accountable advisory relationship rather than coordinating separate electrical, firmware, and FPGA consultants. Leadership brings a stated 150-plus combined years of experience concentrated in a small, senior team.
