Sirin Software vs Timesys: overview
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.
Timesys
Timesys Corporation was founded in 1996 by principals associated with Carnegie Mellon University and built one of the first real-time-enhanced embedded Linux distributions. Headquartered in Pittsburgh, Pennsylvania with roughly 60 employees, Timesys built a long-running specialty in embedded Linux security, engineering services, and long-term maintenance tooling. In December 2023 the company was acquired by Lynx Software Technologies, and buyers evaluating Timesys today should confirm current organizational structure and service continuity directly, since acquisitions of this kind typically bring some integration transition period.
