Born on November 19, 1976 at St. Louis, Missouri,. 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.
Dorsey approached a now-defunct Silicon Valley company called Odeo to pitch the concept. “He came to us with this idea: ‘What if you could share your status with all your friends really easily, so they know what you’re doing?'” said Biz Stone, a former Odeo executive. 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: “just setting up my twttr.” Dorsey was named the company’s chief executive officer.
In 2010, Twitter had more than 105 million users who together tweeted some 55 million times a day. Dorsey, however, had set his sights on other projects. He became an investor in the social networking company Foursquare and launched a new venture, Square, which allows people to receive credit card payments through a tiny device plugged in to their mobile phone or computer. Twitter may have already revolutionized the way that people communicate, but Dorsey isn’t done yet.
My goal is to simplify complexity. I just want to build stuff that really simplifies our base human interaction.
