Timesys vs Developex: overview
Timesys
Timesys came out of Pittsburgh in the mid-1990s, with founders tied to Carnegie Mellon University, and shipped one of the first real-time embedded Linux distributions. Its business now combines engineering services for open-source embedded software with Vigiles, a tool that tracks vulnerabilities in device software bills of materials. Lynx Software Technologies acquired Timesys in December 2023 and said all Timesys products would remain supported. The firm suits Linux-based devices that have to meet the security and SBOM rules arriving in the US and EU.
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.
