Why work for us

AddThis is an American technology company based in Vienna, Virginia. The company operates AddThis.com, a social bookmarking service that can be integrated into a website with the use of a web widget. Once the widget is added, visitors to the website can bookmark an item using a variety of services, such as Facebook, MySpace, Google Bookmarks, Pinterest, and Twitter. The site reaches 2.1 billion unique visitors monthly and is used by more than 15 million web publishers. The company changed its name from Clearspring in May 2012. AddThis was purchased by Oracle Corporation on January 5, 2016. Clearspring Technologies was founded in 2004 by Carnegie Mellon University graduate students Hooman Radfar and Austin Fath in Pittsburgh, Pennsylvania. The company began as an R&D and consulting concern focused on commercializing research concepts around the semantic web and social networks. Initial funding came primarily from grants and consulting projects, as well as from friends, family and a US$100,000 investment from Idea Foundry. Its first product was Semantic Start Page, a customizable, browser-based dashboard that displayed information and news. Users could add widgets from publishers across the web and share content across their social graph. AddThis LLC was founded in 2006 by Dom Vonarburg. By 2007, AddThis had served more than 100 million widgets to websites, with website growth at 100 percent per month and some two million views a day.
