Sirin Software vs QuEST Global: 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.
QuEST Global
QuEST Global was founded in 1997 and is headquartered in Singapore, having grown into a large product engineering and lifecycle services company operating in more than 18 countries with over 90 delivery centers. The firm serves a very broad range of industries — aerospace and defense, automotive, energy, hi-tech, healthcare, rail, and semiconductors — with embedded engineering as one capability within end-to-end silicon and embedded engineering services offered to chipmakers and industrial clients. Reported employee counts vary substantially by source, from roughly 21,500 to over 32,000, reflecting the difficulty of pinning down an exact figure for a firm this size.
