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.
In 2008, Clearspring acquired AddThis LLC, with the intent of creating a single content sharing platform for publishers under one brand: AddThis. The combined platform per Comscore was 254 million unique users. Clearspring upgraded AddThis with widget-sharing capabilities from LaunchPad, then discontinued the LaunchPad offering, reaching 600 million unique users by the end of 2009.
In 2010, the company launched the Clearspring Audience Platform, a service for brand marketers to deliver interest-based display advertising across the web, which topped 1 billion unique users and was used by over 8 million unique domains. Clearspring acquired data science company XGraph in 2011. In September, the company hired a new CEO, Ramsey McGrory, formerly of RightMedia and Yahoo!, with co-founder Radfar becoming executive chairman.
