Williams, Stone and Noah Glass co-founded Obvious Corporation, which then spun off Twitter Inc. with Dorsey as the CEO.
On October 16, 2008, Williams took over the role of CEO, while Dorsey became chairman of the board. On March 28, 2011, Dorsey returned to Twitter as Executive Chairman after Dick Costolo replaced Williams as the CEO. On June 10, 2015, Costolo announced that he was resigning as CEO of Twitter effective July 1, 2015. Dorsey would assume the post of Interim CEO upon Costolo's departure. He was named permanent CEO of Twitter on October 5, 2015.
Dorsey developed a small business platform to accept debit and credit card payments on a mobile device called Square, released in May 2010. The small, square-shaped device attaches to iPhone, iPad, iPod Touch, or Android devices via the headphone jack, and as a mini card reader allows a person to swipe their card, choose an amount to transfer to the recipient and then sign their name for confirmation. Square is also a system for sending paperless receipts via text message or email, and is available as a free app for iOS and Android OS.
