Hank Green Speaking Fee: $75,000 to $100,000

You most likely know Hank Green as the Internet’s science guy. With a combined social media following of over 20 million people, he’s somehow done it mostly with educational content, sharing his excitement about everything from microbes to supernovae. Hank is also a best-selling science fiction novelist, an astute observer and critic of online media, and the co-founder and CEO of Complexly which produces SciShow, Crash Course, and nearly a dozen other educational YouTube channels. Recently, he also created “The Awesome Socks Club” a charity sock subscription that has over 60,000 paying subscribers and donates more than one million dollars to charity every year. All of this began when he and his brother, novelist John Green, began making YouTube videos in 2007. Their pioneering project invented many of the forms of online video. Not many of those early creators are still at it a decade and a half later, but John and Hank seem perpetually able to find success in whatever new platform arises. Along the way, they started VidCon, the largest convention for people who create online video, as well as Subbable, a crowd-funding platform for creators that was acquired by Patreon. Hank loves to speak on science and science communication, education, online video creation, the influencer industry, the societal costs and benefits of social media, running small creative businesses, creative business models, and you probably shouldn’t get him started on pelicans. Hank lives in Montana with his wife and son, so he can also talk about that!
