Silver Lake and Sequoia-backed Unity, a platform for creating and operating interactive, real-time 3D content, completed the merger with ironSource, a business platform that empowers mobile content creators, in a $4.4bn deal. Once closed, current Unity stockholders will own approximately 73.5% and current ironSource shareholders will own approximately 26.5% of the combined company. “We’re happy to welcome ironSource to the Unity family and get a step closer to our goal of being the leading platform for a world with more creators in it. Together, we offer a complete ecosystem for developers to successfully realize and achieve their goals – no matter where they are in the development cycle," John Riccitiello, Unity CEO.
