Softeq vs Developex: overview

Softeq

Chris Howard founded Softeq in Houston in 1997, and the company now employs several hundred people across the US and Europe, with directory estimates between 250 and 500. Its embedded department did years of low-level firmware work for SK Hynix, and current job postings still mention NAND flash controllers, SSDs and eMMC devices. Alongside that, Softeq builds IoT hardware, mobile apps and web platforms, and runs a venture fund for hardware startups. The firmware team is one of several business lines, which suits buyers who want firmware and apps from the same US contract.

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.
