USA Firmware vs Sii Poland: overview
USA Firmware
USA Firmware was founded in 2011 by CEO Bob Scaccia and is based in Brecksville, Ohio, with roughly 17 employees across North America and Asia. The firm's managed design services combine electrical engineering, firmware, FPGA design, and embedded Linux for consumer, commercial, and healthcare product companies, and it appeared on Inc. magazine's Inc. 5000 list of fastest-growing private US companies. Its small team size keeps engagements senior-led, though it also caps the number of large programs it can run in parallel.
Sii Poland
Sii Poland was founded in 2006 and is headquartered in Warsaw, Poland, reporting more than 7,500 specialists company-wide. Firmware and embedded systems R&D form a dedicated practice within a much larger IT services and engineering business that also covers automotive, telecom, and enterprise software, positioning Sii as a scale option for programs that need large, sustained staffing rather than a boutique specialist team. That scale is the firm's clearest advantage and also its clearest trade-off: a small firmware project competes for attention against far larger enterprise accounts.
