Integra Sources vs LTTS: overview

Integra Sources

Integra Sources, founded in 2014, is a compact turnkey hardware-and-firmware shop with public sources disagreeing on both its exact headquarters (most list Astana, Kazakhstan) and current headcount (roughly 24 to 51 employees). Kazakhstan is an unusual but genuine offshore-cost outsourcing base — outside the more commonly discussed Eastern Europe/South Asia corridors — and the firm reports 250+ completed IoT and embedded projects, a useful volume signal for a small team at this cost tier.

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.

- No public case studies with named enterprise clients to independently verify scale claims
LTTS
+ Publicly-listed company (NSE/BSE) with governance and financial transparency most private outsourcing vendors can't provide
+ 22 global design centers and 23,800+ engineers support very large, multi-region outsourcing programs

- Embedded and semiconductor engineering is one of several business lines rather than the firm's sole focus, competing internally for resourcing
- Scale suits large enterprise outsourcing programs better than small or early-stage engagements
- No published rate card or minimum engagement figure
