In 2015, UTA hired a dozen agents from Creative Artists Agency in what was widely characterized in the media as a "midnight raid". Creative Artists Agency filed a lawsuit in response. Also in that year, the company took a minority investment from Jeffrey W. Ubben, founder and CEO of ValueAct Capital, who became a non-voting UTA board member. ValueAct also was invested in 21st Century Fox, Adobe Systems, CB Richard Ellis, and Microsoft at the time. UTA acquired The Agency Group (TAG), the world's largest independent music agency, in August 2015. TAG had approximately 95 agents working in cities including London, Los Angeles, and New York, and brought around 2,000 artists into UTA's client portfolio, including Muse, Paramore and The Black Keys. UTA expanded its New York City offices in 2016.
