On October 22, 2014 Progress Software announced its acquisition of Telerik.[4] The acquisition was finalized on December 1, 2014.



Telerik was founded in 2002 by four graduates of American University in Bulgaria and Technical University of Sofia.[5] Initially focused on providing outsourced software development for foreign and Bulgarian companies,[5] the company shifted its direction to the creation of application development tools. Its first product, RAD editor (rapid application development),[6] was a web page editor designed to support the then recently launched Microsoft technology, ASP.NET. The company then expanded its offerings to include user interface (UI) navigation controls, and the Telerik Sitefinity content management system a few years later.[7] Based upon developer interaction, Telerik developed tools targeted to support other .NET technologies, such as ASP.NET AJAX, ASP.NET MVC, WPF, Silverlight and Windows/Windows Phone.[8] Telerik introduced support for HTML5 and JavaScript in 2011 with its Kendo UI product,[9] coinciding with expected industry growth in mobile adoption.[10]



Company growth came by way of hiring in Bulgaria, as well as expansion and acquisition abroad:[11]

  • 2008 Germany: Acquired Vanatec GmbH, an enterprise-grade ORM provider[12]
  • 2010 USA: Merged with ArtOfTest, adding the Test Studio product[13]
  • 2010 Canada: Acquired TeamPulse, via a partnership deal with Imaginet[14]
  • 2011 UK and Australia: Expansion[15]
  • 2012 USA: Acquired Fiddler, a web debugging proxy[16]
  • 2013 Denmark: Acquired EQATEC Analytics, a software analytics suite[17]

As of 2013, Telerik has 800 employees in 11 offices,[18] led by co-CEOs Vasil Terziev and Svetozar Georgiev,[19] and Chief Product Officer Aaron Mahimainathan.[20]

On October 22, 2014 Progress Software announced its acquisition of Telerik, for $262.5 million.[4]
