Integra Sources vs Tata Elxsi: overview

Integra Sources

Integra Sources, founded in 2014, is a compact custom 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, depending on the source). At this size, turnkey delivery — electronic design, PCB layout, FPGA, embedded firmware, and kernel/driver development for Windows, Linux, macOS, and Android — all under one small team is the actual value proposition: no coordinating separate hardware and software agencies, which matters more for a startup buyer than choosing between generalist scale options.

Tata Elxsi

Tata Elxsi was incorporated in 1989 in Bangalore, India and has grown into a 13,000+ engineer engineering R&D firm spanning automotive, media & telecom, healthcare, and transportation. This is generalist-conglomerate scale under the Tata Group umbrella — real automotive embedded capability exists, but it competes for resourcing against equally significant media and healthcare R&D lines, a structural reality worth confirming directly rather than inferring from company-wide scale.
