LTTS vs Sirin Software: overview
LTTS
L&T Technology Services was incorporated in 2012 as a subsidiary of the Larsen & Toubro Group (with engineering heritage tracing back to 2006 as L&T Integrated Engineering Services) and went public via IPO in 2016. Headquartered in Vadodara, India, LTTS reports roughly 23,800 engineers and technologists across 22 global design centers, with embedded systems and semiconductor engineering as one of several business lines alongside automotive engineering, industrial IoT, manufacturing plant engineering, and medical engineering. The scale and public-company governance make LTTS a fit for large enterprise programs, though embedded work competes for attention against several other major practice areas.
Sirin Software
Sirin Software was founded in 2014, headquartered in Pompano Beach, Florida, with R&D centers in Kyiv and Ivano-Frankivsk, Ukraine, and a team of roughly 30-50 engineers depending on the source. The firm specializes in SDKs, firmware, middleware, and drivers for semiconductor companies and IoT product teams, with named depth in wireless connectivity stacks including Wi-Fi, BLE, Matter, UWB, NFC, and LoRaWAN, and embedded software stacks including Linux, Zephyr, FreeRTOS, and ThreadX. This wireless-protocol depth is Sirin's clearest specialization relative to broader embedded generalists on this list.
