MrBeast

Who he is: 

MrBeast (Jimmy Donaldson) is an American YouTuber, entrepreneur, and philanthropist known for high-energy challenge videos and large-scale giveaways. His main channel is currently the most-subscribed to on YouTube. He also founded the nonprofit Beast Philanthropy and helped launch creator-led campaigns, such as #TeamTrees and #TeamSeas. 

Why he matters: 

MrBeast reshaped what a creator can do by reinvesting revenue into ever-bigger ideas and pairing entertainment with measurable impact. #TeamTrees has funded the planting of 24 million+ trees, while #TeamSeas has raised over $33 million to remove ocean trash—evidence that online communities can mobilize real-world change. For kids, he’s a case study in how creativity + data + teamwork = large-scale problem solving.
