Timesys vs Spyrosoft: 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.
Spyrosoft
Spyrosoft was established in Wrocław in 2016 and grew quickly to more than 1,500 staff and roughly $122 million in 2024 revenue across about 15 offices. Its embedded unit works on HMI software, automotive systems, EV-charging firmware testing and embedded security, including secure boot and OTA updates. It also has a defence and cybersecurity line. The firm is a good fit for EU buyers who need Polish delivery and a mix of embedded and application engineers.
