Twitter founder jack dorsey

39 year old Jack Dorsey is one of the co-founders of micro-blogging social media site Twitter, and is also the CEO of the financial and merchant services provider, Square Inc. He is an American businessman and web developer.

Dorsey, born on the 19th November of ‘76, spent most of his childhood in his hometown, St. Louis, Missouri. He soon became interested in dispatch routing, a process for assigning vehicles to employees and customers, by the age of thirteen.

Dorsey began his tertiary education at the Missouri University of Science and Technology, and then later transferred to New York University, where he first thought up the idea that would later become Twitter.

He moved to California to continue his work as a programmer in dispatching. In 2000, he started his own company in Oakland to dispatch taxis, couriers and emergency services from the internet. Some of the open source dispatch logistics and routing software he developed is still used today by some taxi cab companies.
Over the years, he expanded his idea for a realtime Web-based short message communication service. He partnered with Evan Williams, Biz Stone and Noah Glass to found Twitter (originally named “twttr”) which was launched on July 15th 2006. Dorsey served as the company’s CEO until 2008, when he was replaced by Williams and became the company’s chairman of the board, and later the Executive Chairman. Today Twitter is worth over US$664 million and is one of the most visited websites on the web with an Alexa Ranking of 8.

In 2010 Dorsey launched Square, a small business platform which accepts debit and credit card payments on mobile devices. The mobile devices attach to smartphones and tablets. Dorsey is the current CEO with Square having an estimated value of US$3.2 billion.

He was named as one of the top 35 innovators in the world under the age of 35 in 2008 (MIT Technology Review). He also received the “Innovator of the Year Award” from the Wall Street Journal in 2012. He is also a member of the board of directors at the Walt Disney Company. Dorsey’s personal net worth is approximately US$2.5 billion.


Jack Dorsey’s ideas have led to the development of two companies which provide services that have transformed the way we interact and communicate. His success proves that if you have a vision, it can become a reality.
