Promwad vs ARi: 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.
ARi
ARi traces its engineering roots to 2001 and began operating under the ARi brand in 2006, headquartered in East Peoria, Illinois, with seven additional locations across North America and Asia Pacific; the company reports more than 1,100 employees. Embedded software and firmware sit inside a much broader industrial engineering business that also covers mechanical product design, manufacturing engineering, industrial automation, and robotics, so ARi suits a client whose project spans hardware, firmware, and manufacturing rather than firmware in isolation. Its scale supports large industrial programs that a boutique firmware firm could not staff alone.
