Integra Sources vs Elinext: 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.

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.
