L&T Technology Services vs Elinext: overview

L&T Technology Services

L&T Technology Services (LTTS) is the listed engineering services subsidiary of India's Larsen & Toubro group. It reported more than 23,600 employees at the end of 2025, across 22 global design centres. Embedded systems and VLSI design are among its core business segments, with more than 20 years of embedded work behind them, and its clients include automotive, medical, industrial and telecom OEMs. Like the other large firms on this list, it wins on capacity and process maturity and loses on flexibility for small jobs.

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.
