What is LTTS?
L&T Technology Services was incorporated in 2012 as a subsidiary of the Larsen & Toubro Group (with engineering heritage 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 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. For a procurement team, the publicly-listed status is a genuine differentiator versus most other firms on this list — audited financials and governance disclosures that a private consultancy can't provide — but it also means embedded work competes internally for resourcing against several equally large business lines.
LTTS works primarily with clients in Automotive, Industrial IoT/Manufacturing, Medical devices, Transportation sectors. Its primary differentiator is: Publicly-listed engineering R&D scale (23,800+ engineers) backed by the L&T Group, spanning embedded, automotive, and industrial IoT.
