Spyrosoft vs Elinext: overview

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.

Elinext

Elinext was founded in 1997 by Dr. Khoa Nguyen and now reports about 700 employees, with delivery centres in Poland, Georgia, Kazakhstan, Vietnam and Uzbekistan. Sources disagree on its headquarters (Warsaw and Syosset, New York both appear); this review uses Warsaw. Embedded software development and IoT are listed services, and one client testimonial describes firmware for transferring data between sensors and a user interface. Most of its business is enterprise, web and mobile development, which makes it a generalist pick for firmware.
