Clearspring Announces Audience Delivery of 200MM US Uniques Across Top DSPs and Exchanges

MIG, Invite, DataXu and Others Get Real-Time Access to Social Influencers and Intenders Across Multiple Platforms

MCLEAN, VA--(Marketwire - Apr 25, 2011) - Clearspring Technologies, Inc., provider of the largest online content sharing platform AddThis, announced today that it is now delivering its audiences of influencers and intenders to all major demand-side platforms and the leading ad exchange. Clearspring's Audience Platform, announced last August, is now available on demand-side platforms including WPP's Media Innovation Group (MIG), Invite Media, MediaMath, DataXu, and Turn. Yahoo's market leading Right Media Exchange (RMX) is also now the first ad exchange to utilize Clearspring's audiences. These relationships bring Clearspring's highly targeted transparent audiences to media buyers all over the Web.

Brian Lesser, SVP and General Manager of the MIG, said, "Clearspring is a key data provider that brings differentiated audiences by leveraging a combination of scale, micro targeting, and social data that is valuable and hard to find in combination."

Through its Audience Platform, Clearspring leverages its proprietary real-time data processing engine to aggregate and synthesize anonymous influence and intent data from across the AddThis platform in order to build and deliver valuable audiences to publishers and advertisers. AddThis is currently used by over 9MM domains reaching 1B unique users monthly. Advertisers and publishers can use this anonymous data to reach interest and intent based audiences in categories like movies, automotive, telecom, as well as social audiences targeting influencers.

"Advertisers want to make every impression they buy count -- so reaching the right audiences at the right time across the growing set of display inventory is key," said Peggy Fry, Chief Revenue Officer for Clearspring. "Step one was creating and delivering socially connected audiences of intent and interest at scale. Step two is making our audiences available everywhere and easy to buy -- and that's what we're announcing today."

AddThis is the largest sharing platform on the Web and mobile with more insights into users' "likes," interests and purchase intent than any other third-party sharing platform. "Right Media is working with Clearspring to deliver its valuable audiences to Exchange members and enable them to better connect with consumers online," remarked Ramsey McGrory, VP, Yahoo! NA Marketplaces and Head of Right Media. "Audience Sharing which we introduced on the Exchange last fall enables us to aid buyers and sellers like Clearspring to share, manage and monetize their unique audiences at scale, further reinforcing our position as the leading display advertising exchange."

Audiences available via Clearspring are privacy-safe. Clearspring recently made several moves to ensure privacy and transparency in the way it uses and shares its data. The AddThis platform recently was accepted for membership into the NAI. Clearspring also announced implementation of the EVIDON platform as part of its support of the Digital Advertising Alliance's Online Behavioral Advertising (OBA) guidelines.
