St. Louis , the son of Marcia (Smith)
and Tim Dorsey. He is of part Italian descent. His father worked
for a company that developed mass spectrometers and his mother was a
homemaker. He was raised
Catholic , and his uncle is a Catholic
priest in Cincinnati. He went to
Catholic high school, at Bishop
DuBourg High School .
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 many taxi cab companies. Dorsey attended
Missouri University of Science and Technology before subsequently
New York University
New York University , but he dropped out. He first
came up with the idea that became
Twitter at New York University.
While working on dispatching as a programmer, he later moved to
Biz Stone and Dorsey accepting a Crunchie award
for best mobile startup
In Oakland in 2000, Dorsey started his company to dispatch couriers,
taxis, 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
When he first saw implementations of instant messaging , Dorsey
wondered whether the software's user status output could be shared
among friends easily. He approached
Odeo , which at the time happened
to be interested in text messaging . Dorsey and
Biz Stone decided
that SMS text suited the status message idea, and built a prototype of
Twitter in about two weeks. The idea attracted many users at
investment from Evan Williams who had left
Google after selling Pyra
Labs and Blogger .
Twitter Dorsey in 2008 Dorsey at a Twitter
Town Hall during 2011 alongside United States President
Williams, Stone and Noah Glass co-founded Obvious Corporation, which
then spun off
Twitter Inc. with Dorsey as the
CEO . As chief
executive officer, Dorsey saw the startup through two rounds of
funding by the venture capitalists who backed the company. He
reportedly 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, even 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 describes his three guiding principles,
which he says are shared by the company, as simplicity, constraint and
On October 16, 2008, Williams took over the role of CEO, while
Dorsey became chairman of the board. On March 28, 2011, Dorsey
Twitter as Executive Chairman after
Dick Costolo replaced
Williams as the CEO. On June 10, 2015, Costolo announced that he was
Twitter effective July 1, 2015. Dorsey would
assume the post of Interim
CEO upon Costolo's departure. He was named
Twitter on October 5, 2015. On the day after the
controversy about Twitter's new algorithms for tweets, Dorsey
responded to the trend saying 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
move was an attempt to entice new users since the number of tweets per
day had dropped to about 300 million in January 2016 compared to about
500 million in September 2013 and its peak of 661 million in August
On November 17, 2016, Dorsey tweeted a public apology for an
automated system error that allowed a hate ad to appear on Twitter
that violated Twitter's user policy. The error occurred within one day
Twitter suspending multiple accounts associated with the alt-right
On November 22, 2016, Dorsey was briefly suspended from his own
Twitter user account with 3.9M followers. After restoring the account
Dorsey tweeted the suspension was due to an "internal mistake".
In February 2017, Dorsey and Executive Chairman Omid Kordestan
matched a $530,000 donation to the American Civil Liberties Union
(ACLU) raised by
Twitter staffers. Their match brought the total
donation to $1.59 million.
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. The
company grew from 10 employees in December 2009 to over a hundred
employees by June 2011. Square's office is located on Market Street in
San Francisco . In September 2012,
Business Insider magazine valued
Square Inc. at $3.2 billion. Dorsey is
Square, Inc. On

Stock Exchange .

60 Minutes called "The Innovator: Jack Dorsey"
which aired during March 2013. In 2013, talking to
CNN , Dorsey
expressed admiration for
Michael Bloomberg and his reinvention through
design and simple interfaces of what it means to be mayor. Dorsey
thinks becoming mayor of New York City is an aspiration that would
raise the bar for him. He served as a judge for New York City Mayor
Michael Bloomberg 's
NYC BigApps competition in 2011. Dorsey is an
on-record donor to Democratic Party candidates.
