USA Firmware vs Sigma Software Group: overview
USA Firmware
USA Firmware was founded in 2011 by Bob Scaccia and operates from Brecksville, Ohio with a small team of around 17 people. Its managed design services combine electrical engineering, firmware, FPGA design, embedded software, and Linux expertise into a single discovery-through-production-enablement process, aimed at clients who want one accountable partner rather than coordinating separate electrical, firmware, and FPGA vendors. Leadership brings a stated 150-plus combined years of experience, concentrated in a small team rather than spread across a large organization.
Sigma Software Group
Sigma Software Group was founded in Kharkiv, Ukraine in 2002 by five friends and now employs more than 1,100 people across Ukraine, Sweden, Poland, and the United States. In 2006 the Swedish IT conglomerate Sigma Group acquired a 60% stake in the company, an ownership structure that has held since; the remaining 40% stays with the original Ukrainian founders. Its embedded and IoT services cover application development, firmware, middleware, device drivers, and human-machine interfaces, delivered as one practice within a much larger portfolio spanning gaming, aviation, and telecom software.
