Promwad vs Developex: overview

Promwad

Roman Pakholkov started Promwad in Minsk in 2004 to design mass-produced electronics on system-on-chip platforms, and the company has since moved its business into the EU, with headquarters in Essen, Germany and a client delivery office in Lithuania. It reports more than 100 employees across 15 countries (per company website; independently unverifiable) and over 500 completed projects. Work spans schematic and PCB design, FPGA logic, embedded Linux, RTOS firmware and preparing designs for factory production. Broadcast video, telecom, automotive and industrial automation are its most frequently cited sectors.

Developex

Developex has written software for hardware companies since 2001, and its client list leans toward consumer electronics and peripheral makers who need firmware, drivers and the desktop or mobile utilities that configure their devices. The company is based in Kyiv with offices listed in Munich, Kraków and Zagreb, and directory estimates put the team at about 250 to 350 people. A company blog post put its embedded group at more than 30 developers (per company website; independently unverifiable). That makes firmware a real practice inside a larger custom-software business.
