Jack Patrick Dorsey is an American computer programmer and Internet entrepreneur, the co-founder and CEO of Twitter, the founder and CEO of Square, a mobile payments company. Dorsey was born and raised in St. Louis, the son of Tim and Marcia Dorsey, he is of English and Italian descent. His father worked for a company that developed his mother was a homemaker, he was raised Catholic, his uncle is a Catholic priest in Cincinnati. He attended the Catholic Bishop DuBourg High School. In his younger days, Dorsey worked as a fashion model. By age fourteen, Dorsey had become interested in dispatch routing; some of the open-source software he created in the area of dispatch logistics is still used by taxicab companies. Dorsey attended the University of Missouri–Rolla for two-plus years before transferring to New York University, but he dropped out in 1999, one semester short of graduating, he came up with the idea that he developed as Twitter while studying at NYU. While working on dispatching as a programmer, Dorsey moved to California.

In 2000, Dorsey started his company in Oakland to dispatch couriers and emergency services from the Web. His other projects and ideas at this time included networks of medical devices and a "frictionless service market". In July 2000, building on dispatching and inspired in part by LiveJournal and by AOL Instant Messenger, he had the idea for a Web-based realtime status/short message communication service; when he first saw implementations of instant messaging, Dorsey wondered whether the software's user status output could be shared among friends. He approached Odeo. Dorsey and Biz Stone decided that SMS text suited the status-message idea, built a prototype of Twitter in about two weeks; the idea attracted many users at Odeo and investment from Evan Williams, who had left Google after selling Pyra Labs and Blogger. Williams and Noah Glass co-founded Obvious Corporation, which spun off Twitter, Inc. with Dorsey as the Chief Executive Officer. As CEO, Dorsey saw the startup through two rounds of funding by venture capitalists.

He lost his position for leaving work early to enjoy other pursuits, such as yoga and fashion design. As the service began to grow in popularity, Dorsey chose the improvement of uptime as top priority over creating revenue – which, as of 2008, Twitter was not designed to earn. Dorsey described the commercial use of Twitter and its API as two things that could lead to paid features, he says his three guiding principles, which he says the company shares, are simplicity and craftsmanship. On October 16, 2008, Williams took over as CEO. On March 28, 2011, Dorsey returned to Twitter as executive chairman after Dick Costolo replaced Williams as 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. On the day after the controversy about Twitter's new algorithms for tweets, Dorsey said it was only a hoax. In May 2016, Dorsey announced that Twitter would not count photos and links in the 140-character limit to free up more space for text.

This was an attempt to entice new users, since the number of tweets per day had dropped to about 300 million in January 2016 from about 500 million in September 2013 and its peak of 661 million in August 2014. On November 22, 2016, Dorsey was suspended from his own Twitter account with 3.9 million followers. After restoring the account, Dorsey tweeted that the suspension was due to an "internal mistake". In February 2017, Dorsey and Executive Chairman Omid Kordestani matched a $530,000 donation to the American Civil Liberties Union raised by Twitter staffers, their match brought the total donation to $1.59 million. In March 2018, Dorsey announced that an improved version of the verification system is coming to Twitter; the purpose of redesigning verification is to let people verify more facts about themselves, emphasizing proof of identity. The overhaul was not in place before the U. S midterm election of 2018 to help in verifying the identities of the candidates. In September 2018, Dorsey testified before the Senate Intelligence Committee alongside Facebook COO Sheryl Sandberg about meddling in the 2016 presidential election.

Following this testimony, Twitter shares fell 6%. Dorsey met with U. S. President Donald Trump at the White House and discussed Trump's concerns that Twitter had limited or removed some of his Twitter followers, those of conservatives. After the meeting, Dorsey tweeted that their discussion included making Twitter "healthier and more civil". A week earlier, Dorsey took part in a TED talk about the social media platform's spread of abuse and misinformation, which has brought him criticism. On August 30, 2019, Dorsey's personal Twitter account was breached for nearly an hour by a group calling itself the Chuckling Squad and retweeting numerous racist tweets. On October 23, 2019, Twitter's stock price fell by nearly 24%, from $38.83 to $30.75. The reason was an earnings miss off a third-quarter report, which Twitter blamed on ad targeting problems. Dorsey had been making a concerted effort to dampen the effect that Twitter had on political elections, which entailed banning all political ads; this was seen as a large contributor to the drop.

Dorsey announced that, as of November 2019, Twitter would ban all political advertising. The policy applies globally to all marketing campaigns about political issues. Dorsey, along with co-founder Jim McKelvey, developed a small business platform to acce
