Integra Sources vs L&T Technology Services: 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.
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.
