Telerik

Telerik is a Bulgarian company offering software tools for web, mobile, desktop application development, tools and subscription services for cross-platform application development. Founded in 2002 as a company focused on .NET development tools, Telerik also sells a platform for web, hybrid and native app development. 

Telerik's first product, RAD editor (rapid application development), was a web page editor designed to support the Microsoft ASP.NET technology. The company then expanded its offerings to include user interface (UI) navigation controls, and the Telerik Sitefinity content management system a few years later. Telerik developed tools targeted to support other .NET technologies, such as ASP.NET AJAX, ASP.NET MVC, WPF, Silverlight and Windows/Windows Phone. Telerik introduced support for HTML5 and JavaScript in 2011 with its Kendo UI product.

Now, Progress Telerik toolkits include more than 1100 UI components for all .NET Frameworks, as well as multiple themes, skins and customization options for web, cross-platform mobile and desktop development.
