rinf.tech vs Elinext: overview

rinf.tech

rinf.tech was founded in Bucharest in 2006 and describes itself as a 600-plus person organisation, with delivery centres in Bucharest, Timișoara, Kyiv and Sofia and offices in Germany, France and the US; a delivery office in India opened in 2025. R&D and embedded systems is one of several technical divisions, alongside enterprise applications, robotics and automotive. Job listings point to firmware in multicore environments and NPU accelerator work. For EU buyers it offers nearshore embedded capacity under EU contracts.

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.
