From his friendship with Elon Musk to quashing rumors about sending his beard hair to rapper Azealia Banks, Twitter founder Jack Dorsey leads an interesting life.
Dorsey has had a turbulent career in Silicon Valley. After cofounding Twitter on March 21, 2006, he was booted as the company's CEO two years later, but returned in 2015 having set up his second company, Square — which he rebranded as Block in 2021.
He led Twitter through the techlash that has engulfed social media companies, testifying before Congress multiple times and later stepping down as CEO of Twitter in 2021, as well as eventually encouraging Musk's Twitter acquisition the following year. Dorsey continues to lead Block, where in April 2022 he changed his title from "CEO" to "Block Head."
The tech entrepreneur has provoked his fair share of controversy and criticism over the years and like some other billionaires, he owns a stunning house, dates models, and drives fast cars.
Here's what we know about Dorsey's career rise and life outside of work.
