McLean, Va. - August 5, 2010 — Clearspring Technologies, Inc., provider of the comScore ranked #1 content sharing platform AddThis, announced today the launch of its Audience Platform enabling advertisers and publishers to reach audiences of influencers and intenders.

Since January, Clearspring has worked with the biggest brands and agencies to deliver highly targeted audiences to improve the performance of video and display campaigns through the Audience Platform. Leveraging demand-side platforms and ad exchanges, Clearspring's Audience Platform helps advertisers to more effectively reach audiences in categories like movies, automotive, telecom, social influencers and more.

"Momentum is building around real-time bidding platforms, as agencies move towards more accountable and transparent ways of purchasing media. The Clearspring Audience Platform provides broad and deep audiences, essential to unlocking an effective strategy," said Brendan Moorcroft, CEO Mediabrands' Cadreon. "With their targeting capability based on a user's purchase intent, interest and influence, Cadreon has seen strong performance for many of our clients."

Clearspring's AddThis platform is used by over 1.5MM unique domains to share webpages, widgets, photos, and video to over 300 social services like Facebook, Twitter, Digg, MySpace and more. With the Audience Platform, Clearspring is leveraging its proprietary real-time data processing engine to aggregate and synthesize influence and intent data from across the platform, in order to build and deliver valuable audiences to publishers and advertisers.

"Our focus has been to connect people via content by powering social sharing across the web. Our sharing platform, AddThis, today reaches over 1 billion people online and drives more sharing than any other publisher platform of its kind," said Hooman Radfar, Chief Executive Officer of Clearspring. "Our Audience Platform technology leverages our huge reach and proprietary analytics engine to provide advertisers and publishers with incredibly valuable audiences, as well as provides consumers with advertisements that are of interest, without leveraging personally identifiable information."

Social sharing and audience development are valuable tools for publishers and advertisers to deliver more relevant content and advertisements, which improves the user experience. Clearspring maintains the highest level of user privacy. Clearspring is actively involved with organizations like the Interactive Advertising Bureau to set consumer-friendly interest-based ad standards and complies with the Network Advertising Initiative standards. "Our network presents us with a tremendous opportunity to improve the user experience online, but with that opportunity comes a responsibility, that we take very seriously, to make consumer privacy a top priority," continued Radfar.

Publishers using AddThis will also be able to leverage the Audience Platform. These publishers will have access to unique aggregated insights about audiences visiting their site. Using this platform, publishers will be able to create more innovative programming experiences or deliver more relevant advertising opportunities to consumers.

"The AddThis sharing platform is helping to increase traffic and engagement across our AOL Network of sites and delivers a great sharing consumer experience for our users. We're excited to now be able to leverage the Clearspring Audiences to improve the way we connect our advertising with our audiences and their social network of friends and followers," said Sun Sachs, VP AOL Media.
