Integra Sources vs Tata Elxsi: 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.

Tata Elxsi

Tata Elxsi, incorporated in 1989 in Bangalore, India, has grown into a 13,000+ engineer engineering R&D firm spanning automotive, media & telecom, healthcare, and transportation across 16 countries. As a Tata Group company, it offers offshore-India outsourcing scale backed by one of India's most established industrial conglomerates — relevant for buyers who weight corporate stability heavily in offshore vendor selection.
