Jimmy Donaldson (born May 7, 1998), better known online as MrBeast, is an American YouTuber, entrepreneur and philanthropist. He has been credited with pioneering a genre of YouTube videos that center on expensive stunts. He is also the co-creator of Team Trees, a fundraiser for the Arbor Day Foundation, which has raised over $72 million. He is managed by the Dallas-based talent management company Night Media. Donaldson began posting videos to YouTube in early 2012 at the early age of 13, under the handle “MrBeast6000”; his early content ranged from Let’s Plays to “videos estimating the wealth of other YouTubers”. He went viral in 2017 after his “counting to100,000” video earned tens of thousands of views in just a few days, and has become increasingly popular ever since, each of his videos gaining tens of millions of views. Over time, his style of content diversified to include expensive challenge videos that reward thousands of dollars, donation videos involving a lot of money, videos either with arduous tasks or survival, and original vlogging videos. Once his channel took off, Donaldson hired several of his childhood friends to help him run the growing brand. The MrBeast team is currently made up of 30 people.
