2014 Progress Software buys mobile development platform Telerik

Progress Software announced it was buying Telerik for $262.5M. Telerik’s portfolio includes a .net toolbox, a mobile development platform and a CMS called Sitefinity, as well as access to a developer community of over 1.4M people. Progress describes itself as “simplifying the development, deployment and management of business applications on-premise or in the cloud, on any platform or device, connected to any data source.” Last year Progress bought Platform as a Service provider, Rollbase. Then it purchased Modulus, a company that gives it play in Node.js. Today’s purchase of Telerik is another step in that strategy. Telerik will give Progress some serious UI chops it had been lacking and builds on these other tools.
