E van Williams is a highly influential American technology entrepreneur who has played a pivotal role in the creation of three of the most important internet platforms of the modern era: Blogger, Twitter, and Medium. A self-taught programmer from Nebraska, he moved to Silicon Valley and co-founded Pyra Labs, which created the pioneering blog-publishing service, Blogger. The service was acquired by Google in 2003, making Williams a multi-millionaire.

He then went on to co-found Twitter, the microblogging service that would change global communication, and he served as its CEO and later as a board member for many years. After leaving Twitter, he founded his third major venture, Medium, an online publishing platform that aims to provide a home for high-quality, long-form writing. His career has been defined by his deep interest in creating open platforms for communication and self-expression on the internet. His wealth is primarily derived from his large, early stakes in Google and Twitter.
