LTTS vs QuEST Global: 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.
QuEST Global
QuEST Global was founded in 1997 and is headquartered in Singapore, having grown into a large product engineering and lifecycle services company operating in more than 18 countries with over 90 delivery centers. The firm serves a very broad range of industries — aerospace and defense, automotive, energy, hi-tech, healthcare, rail, and semiconductors — with embedded engineering as one capability within end-to-end silicon and embedded engineering services offered to chipmakers and industrial clients. Reported employee counts vary substantially by source, from roughly 21,500 to over 32,000, reflecting the difficulty of pinning down an exact figure for a firm this size.
