Promwad vs Sii Poland: overview
Promwad
Promwad was founded in 2004 and moved its headquarters to Essen, Germany, with engineering centers in Latvia and Serbia and a team in the 101 to 250 employee range. The firm's core work covers embedded software, embedded Linux, hardware design, and FPGA programming, with device driver and board support package engineering delivered as a defined service line rather than an incidental capability. Promwad markets itself as an independent design house, meaning it takes on both firmware-only engagements and full electronics-through-manufacturing programs depending on client scope.
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.
