"Three years ago during my time as CEO of Odeo, I was lucky to be working with a software engineer Jack Dorsey who wasn't afraid to bring up an idea he'd been thinking about for a long time. What if a simple status message was the format for a social communication service? We were exploring various options for Odeo at the time and experimenting with SMS, so the idea was intriguing. Jack teamed up with Biz Stone to design a prototype. This simple idea called Twitter proved increasingly interesting the more we fleshed it out.
After my company Obvious purchased the assets of Odeo which at the time included Twitter from the shareholders, we decided to form Twitter, Inc as a separate company founded by myself along with Jack and Biz. Jack had by then been leading the project for months with Biz's support, and I was intent on pursuing Obvious. With my blessing, the reigns of Twitter CEO were handed to Jack and I accepted a position as Chairman of the Board.
Rising quickly to the challenge, Jack took Twitter through an order of magnitude of growth and two major rounds of financing, while safely navigating some very rocky waters that would have taken even more experienced leaders down with the ship. Jack is a unique individual with a knack for artful minimalism and simplicity, combined with great vision and ambition. We are indeed fortunate to have his guidance."
Jack remains Chairman, said Evan. "We're entering a new phase now and there are new kinds of challenges ahead. Healthy companies acknowledge the need for change even during the best of times. As Twitter grows both internally and externally, we took a good look at our path forward and saw the need for a focused approach from a single leader."
We wish Jack all the best of luck. So, what's he doing now? By the looks of it on Twitter, he's calling his folks.
