Stephen Deleonardis (born August 26, 1998), most famously known as SteveWillDoIt, is an American social media personality, YouTuber, and entrepreneur. He gained initial recognition for his outrageous stunts, challenges involving food and alcohol, and prank videos, often in collaboration with the NELK Boys. His willingness to perform any challenge his audience suggested became the foundation of his personal brand. He attended Oviedo High School and then pursued social media instead of college.
SteveWillDoIt's YouTube channel was initially banned in August 2022 due to violations of YouTube's Community Guidelines related to gambling promotion. After a three-year ban, his channel was reinstated in December 2025. To mark his return, he released a "diss track" aimed at MrBeast, with whom he has publicly feuded. Beyond content creation, SteveWillDoIt is a co-founder of Happy Dad Hard Seltzer, which has become the fourth-largest seltzer brand in America, and is involved with Full Send Clothing. He has an estimated net worth between $5 million and $12 million, with a substantial portion stemming from his business ventures. In late November 2025, SteveWillDoIt appeared on Logan Paul's podcast Impaulsive, but the interview ended abruptly after a contentious discussion.
