Ev Williams.

Ev Williams is the Co-Founder of Twitter (now X), Medium, Blogger, and his latest venture Mozi-making him one of the most consequential serial entrepreneurs in internet history.

Williams co-founded Blogger, one of the first blogging platforms, which was acquired by Google in 2003. He then co-founded Twitter in 2006, serving as CEO from 2008 to 2010 as the platform became one of the most influential communication tools in history. In 2012, Williams founded Medium, the online publishing platform that has become a home for serious thinkers, journalists, and writers, with millions of readers monthly. His newest venture, Mozi, is a private social network for real-world friendships, launched in 2024. Williams's trajectory-creating three of the most important platforms for online communication and publishing over 25 years-demonstrates a rare ability to consistently identify how people will want to communicate as technology evolves. His influence on how hundreds of millions of people share ideas, news, and content is profound and enduring.
