Integra Sources vs Spyrosoft: overview
Integra Sources
Two hardware and software engineers set up Integra Sources in 2014, and it now operates from Astana, Kazakhstan with a team in the low dozens. Its service list covers electronics design, embedded firmware, Linux kernel and driver development, computer vision and robotics, and it has collected a long run of Clutch reviews for IoT and device projects. Rates are below those of the European and US firms on this list. Buyers get engineers comfortable at the register level, though with less of the process documentation that regulated industries expect.
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.
