Taptu  Taptu was a social media and technology company that built platforms, tools and applications that enabled content on touch screen mobile devices, including phones running iOS and Android. Taptu was a privately held company that was founded in Cambridge in 2007 and was funded by DFJ Esprit and Sofinnova. The company was based in Cambridge and Denver, Colorado. In September 2012, Taptu was acquired by Mediafed Ltd. The Taptu service shut down March 31st, 2015, a year before Mediafed went into administration. Taptu's first product was a mobile search engine, provided as a website using html optimised for phones, and dedicated "apps" for iPhone and Android. It was closed in early 2011. Its other product was My Taptu, a social news aggregator that drew heavily on the company’s mobile search heritage but attempts to move them beyond search. According to Taptu, the app, which was available on the iPhone and Android devices, was "aimed at solving information overload," or what Taptu calls "app hopping." It presented all the information that a person "is into" in a "one- stop app" through "streams," or what CNET described as “content playlists.” My Taptu tried to separate itself in the social news space by offering ways of personalization.
