Sirin Software vs LTTS: overview
Sirin Software
Sirin Software, founded in 2014, is headquartered in Pompano Beach, Florida with R&D centers in Kyiv and Ivano-Frankivsk, Ukraine — a deliberate US-front, Ukraine-delivery structure that gives American buyers a single US contracting entity while the actual engineering work happens at Ukraine's substantially lower cost base. This structure is common among boutique outsourcing firms and worth understanding explicitly: the client relationship and invoicing run through the US entity, while day-to-day engineering is offshore.
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.
