The ShareThis button is an all-in-one widget that lets people share any content on the Web with friends via e-mail, AIM, or text message. Shar.es is the URL shortener for ShareThis.com. The widget can also keep an account of personal contacts so that users can send an e-mail, IM, or text message with favorite links to friends.  The button can be deployed on any site to drive traffic, stimulate viral activity, and track the sharing of content. Toolbar versions exist for Firefox, Mozilla Application Suite and Internet Explorer, and customized widgets are available for leading blog publisher sites including Blogger, TypePad and WordPress.
ShareThis was founded by Dr. David E. Goldberg, engineering professor at University of Illinois at Urbana-Champaign, and Tim Schigel, then a Director at Blue Chip Venture Company (“Blue Chip”). ShareThis owns an exclusive license, with the University of Illinois, for Dr. Goldberg’s patent applications in the area of genetic algorithms and machine learning for the purposes of information discovery and learning from sharing behavior. ShareThis has headquarters in San Francisco, CA and Cincinnati, OH. Investors include IllinoisVENTURES and DFJ Mercury.
