Jack Dorsey

Jack Dorsey, born November 19, 1976, is an American web developer and businessman widely known as the creator of Twitter and as the founder and CEO of Square, a mobile payments company. 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. For 2012, The Wall Street Journal gave him the “Innovator of the Year Award” for technology.

Jack Dorsey is best known as the creator of Twitter. Growing up in St. Louis, Dorsey became interested in computers and communications at an early age and began programming while still a student at Bishop DuBourg High School.

He was fascinated by the technological challenge of coordinating taxi drivers, delivery vans and other fleets of vehicles that needed to remain in constant, real-time communication with one another. When he was 15, Dorsey wrote dispatch software that is still used by some taxicab companies today.

After a brief stint at the Missouri University of Science and Technology, Dorsey transferred to New York University. He dropped out of college before receiving his degree. Instead, Dorsey moved to Oakland, California, and in 2000 started a company offering his dispatch software through the Web.

Shortly after starting his company, Dorsey came up with the idea for a site that would combine the broad reach of dispatch software with the ease of instant messaging, and approached a now-defunct Silicon Valley company called Odeo to pitch the concept.

Dorsey, Stone and Odeo co-founder Evan Williams started a new company, called Obvious, which later evolved into Twitter. Within two weeks, Dorsey had built a simple site where users could instantly post short messages of 140 characters or less, known in Twitter parlance as “tweets.” On March 21, 2006, Jack Dorsey posted the world’s first tweet.

In May 2010, Dorsey developed a small business platform to accept debit and credit card payments 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 it allows a person to swipe his or her card, choose an amount to give to the recipient and then sign his or her name for confirmation.

In September 2012, Business Insider magazine valued Square Inc. at $3.2 billion (US).

For Dorsey, It is all one big integrated system, the grand flow of interactions, and he has been thinking about this stuff since he was 8 years old. Success Mr. Dorsey, Success!
