USA Firmware vs Sigma Design: 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 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.
Sigma Design
Sigma Design (operating as SIGMADESIGN) was established in 1994 in Portland, Oregon and is now headquartered in Camas, Washington with approximately 283 employees across five continents. Its advisory scope covers mechanical design, industrial design, testing, and software and firmware engineering, positioning itself as a full product design and engineering partner rather than a firmware-only consultant. For an architecture review that needs to weigh industrial design, mechanical engineering, and firmware decisions together, Sigma Design's breadth and headcount give it more parallel-program capacity than most boutique advisory firms.
