Jack Dorsey was 29 years old when he created twitter, a company now evaluated at 10 billion. Jack joined the computer programing scene when he was 14 years old creating open source software for dispatch services, still used by some taxi services today. Jack attended Missouri university of science and technology for a short time, he then transferred to New York University and soon dropped out. After dropping out he moved to California to start a dispatch website which dispatched taxis and emergency services.

Jack thought of the idea of Twitter after using a social media service called LiveJournal, Jack thought there were many ways to improve it. One day when Jack was sitting in a coffee shop, Evan Williams, the chief executive of Odeo walked in. After talking with Evan, Jack was interested in working at Odeo which was a podcasting company. Jack was hired and pitched his idea of twitter, originally called Obvious. Jack, Evan, and Odeo executive Biz Stone had a simple website made in just two weeks. Jack was named CEO but ran into trouble with keeping the website running, so he was replaced by Evan Williams. Jack was still a company chairman at Twitter, and during that time he developed another product called Square, a way for smartphones to take credit card payments. Square quickly gained popularity and is now evaluated at 3.2 billion dollars, with Jack as the CEO. In 2011 Jack rejoined Twitter to lead product development as Executive Chairman.

Just like Steve Jobs, Jack Dorsey was also kicked out of the company that he founded. Jack didn’t let that hurdle stop him as he went on and created another hit product. Jack is a great entrepreneur because he wasn’t just a one-hit wonder, he created more than one amazing product. Jack started out with humble beginnings and is now a very accomplished man, with a net worth of 2.2 billion
