LTTS vs Promwad: overview

LTTS

L&T Technology Services was incorporated in 2012 as a subsidiary of the Larsen & Toubro Group (with engineering heritage tracing back to 2006 as L&T Integrated Engineering Services) and went public via IPO in 2016. Headquartered in Vadodara, India, LTTS reports roughly 23,800 engineers and technologists across 22 global design centers, with embedded systems and semiconductor engineering as one of several business lines alongside automotive engineering, industrial IoT, manufacturing plant engineering, and medical engineering. The scale and public-company governance make LTTS a fit for large enterprise programs, though embedded work competes for attention against several other major practice areas.

Promwad

Promwad is an electronics design house founded in 2004 by Roman Pakholkov, headquartered in Essen, Germany, with additional engineering centers in Latvia and Serbia and a team of 100+ engineers and managers built over more than two decades. The company positions itself as an end-to-end engineering partner covering hardware design (PCB layout, FPGA), embedded software (Linux and Android embedded systems), and contract manufacturing coordination for customers across Europe and North America, making it a fit for clients wanting hardware and firmware handled by one contracted partner rather than separate vendors.
