Privately owned iSocket, headquartered in the US, was founded in 2008 and operated with approximately 10 employees. Its main product involved advertising services, specifically a technology platform designed to streamline the direct buying and selling of fixed-price, premium, reserved advertising inventory. The platform offered sales automation tools for publishers and order execution tools for advertisers, with the objective of reducing inefficiencies in the manual media sales process. iSocket was acquired by Rubicon Project, which later merged with Telaria to form Magnite.
