Integra Sources vs Tata Elxsi: overview
Integra Sources
Integra Sources, founded in 2014, is a compact custom hardware and firmware development shop reporting 250+ completed IoT and embedded projects despite public sources disagreeing on both its exact headquarters (most list Astana, Kazakhstan) and current headcount (estimates range from roughly 24 to 51 employees). For a technical buyer, the operative pitch is turnkey delivery: electronic design, PCB layout, FPGA, embedded firmware, and kernel/driver development for Windows, Linux, macOS, and Android all sit under one small team, avoiding the vendor-coordination overhead that comes with splitting hardware and firmware across separate suppliers — a meaningful consideration for an early-stage program without in-house hardware engineering to manage that coordination itself.
Tata Elxsi
Tata Elxsi was incorporated on May 5, 1989 in Bangalore, India and has grown into a 13,000+ engineer engineering R&D services firm spanning automotive, media & telecom, healthcare, and transportation across 16 countries. For a technical buyer specifically comparing automotive embedded capability, Tata Elxsi's relevant depth is in autonomous, electric, and connected vehicle technologies including software-defined vehicles — but that automotive practice sits alongside equally large media/telecom and healthcare R&D lines, part of the Tata Group's broader engineering conglomerate, so the automotive team's specific bench strength should be confirmed directly rather than assumed from the parent company's overall scale.
