About
Jack Dorsey co-founded Twitter in 2006 and Square (now Block) in 2009, and is one of very few founders to have taken two companies public and served as CEO of both simultaneously. He was ousted from Twitter in 2008, returned as CEO in 2015, and left in 2021; he sold Twitter to Elon Musk in 2022. He now runs Block and funds Bitcoin and open-protocol work, including Bluesky and Nostr.
