QuEST Global vs LTTS: overview

QuEST Global

QuEST Global, founded in 1997 and headquartered in Singapore, operates over 90 delivery centers across 18+ countries — one of the broadest global outsourcing footprints on this list. Reported employee counts vary substantially by source (roughly 21,500 to over 32,000), itself a sign of a firm too large and diversified for a single precise headcount. Embedded and silicon engineering is one capability among many verticals rather than a dedicated outsourcing specialty.

LTTS

L&T Technology Services, incorporated in 2012 as a subsidiary of the Larsen & Toubro Group, went public via IPO in 2016. Headquartered in Vadodara, India, LTTS reports roughly 23,800 engineers across 22 global design centers — a large-scale offshore-India outsourcing base with public-company financial transparency, though embedded work competes internally for resourcing against several equally large business lines.
