madKast

ShareThis is a social data platform that creates authentic digital experiences by connecting people through content they love.

Recently founded madKast makes it easy for people to share news and blog posts with others via a single click. Users just have to enter their e-mail address to get a madKast widget, which once installed, lets you share the story's URL with your contacts through e-mail, text messaging, instant messaging, or social bookmarking sites. madKast is free, and there is no registration or downloading required to get their widget. The company's founders were also involved in the creation of [Zemble.com](http://www.zemble.com), a free text messaging service, and consider madKast to be a 'brainchild' of Zemble. madKast is an incubating startup for [TechStars](http://www.crunchbase.com/organization/TechStars).
