St. Louis, Missouri, U.S.
Residence San Francisco, California, U.S.
Occupation software designer, entrepreneur

Jack Dorsey (born November 19, 1976) is an American software architect and businessman widely known as the creator of Twitter and as the founder and CEO of Square, a mobile payments company.[3] In 2008, he was named to the MIT Technology Review TR35 as one of the top 35 innovators in the world under the age of 35.[4]

[edit] Early years

Dorsey grew up in St. Louis, Missouri,[5] and by age 13, he had become interested in dispatch routing. Some of the open source software he created in the area of dispatch logistics is still used by many taxi cab companies.[5] He went to high school at Bishop DuBourg High School and attended the Missouri University of Science and Technology before subsequently transferring to New York University, where he first conceived the idea for Twitter.[6]

While working on dispatching as a programmer he later moved to California.[7][8]

In Oakland in 2000, Dorsey started his company to dispatch couriers, taxis, and emergency services from the Web.[9] His other projects and ideas at this time included networks of medical devices and a "frictionless service market".[9] In July 2000, building on dispatching[5] and inspired in part by LiveJournal and possibly by AOL Instant Messenger, he had the idea for a Web-based realtime status/short message communication service.[9]

When he first saw implementations of instant messaging, Dorsey had wondered if the software's user status output could be shared among friends easily.[5] He approached Odeo, who at the time happened to be interested in text messaging.[5] Dorsey and Biz Stone decided that SMS text suited the status message idea, and built a prototype of Twitter in about two weeks.[5] The idea attracted many users at Odeo and investment from Evan Williams[5] who had left Google after selling them Pyra Labs and Blogger.

[edit] Twitter, Inc.

Dorsey, Stone, and Williams co-founded Obvious which then spun off Twitter, Inc.[5] As chief executive officer, Dorsey saw the startup through two rounds of funding by the venture capitalists who backed the company.[10] On October 16, 2008[11] Williams took over the role of CEO, and Dorsey became chairman of the board.[12] On March 28, 2011, Dorsey returned to Twitter as Executive Chairman.[13]

As the service grew in popularity, Dorsey chose improving uptime as top priority,[14] even over creating revenue – which, as of 2008, Twitter was not designed to earn.[15] Dorsey described the commercial use of Twitter and its API as two things that could lead to paid features.[15] His three guiding principles, which are shared by the whole company and through its culture, are simplicity, constraint and craftsmanship.[15]

[edit] Square, Inc.

Dorsey developed a small business platform to accept debit and credit cards on a mobile device called Square. The small, square-shaped device attaches to iPhone, iPad or Android devices via the headphone jack, and as a mini card reader allows a person to swipe their card, choose an amount to give 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.[16]
