Later that year, the company acquired Thinking Space, an Android-based information mapping application, and Cohuman, a social task management service, which the company developed into a collaborative, cloud-based service to complement MindManager called Mindjet Connect or Project Director. In 2011, mobile versions of MindManager were released for both iOS and Android. With the release of version 7, the Windows version of MindManager adopted the ribbon interface first seen in Microsoft Office 2007 and introduced support for Office Open XML. Originally only available for Windows, MindManager expanded to Mac OS X in 2006. In 1999, it was rebranded as MindManager. The software was originally marketed under the name 'MindMan - The Creative MindManager'. Over time, however, Mindjet has developed its own style of mind mapping. The software's mind maps were initially based on the method created by Tony Buzan. Following his release from hospital, Jetter decided to sell the software. Jetter's goal was to develop a program that would overcome the limitations of creating mind maps with pen and paper, such as the inability to easily move items around. The software that became MindManager was originally developed by Mike Jetter in the mid-1990s while he was recovering from a bone marrow transplant to treat leukemia.
