Maker of Leading Sharing Platform Consolidates Brands Around
          AddThis as Company Crosses 1.3B User Milestone

Mclean, Va., May 10, 2012 (GLOBE NEWSWIRE) -- AddThis launches today a
robust set of social plugins, analytics, and audience products to
provide a full suite of sharing and engagement tools for publishers and
brands. The announcements from the company, formerly known as
Clearspring, accompany consolidation of the company's brands under
AddThis and come with new milestones for unique users and domains.

As the industry leader on the social open web, AddThis is now used by
14 million domains and reaches over 1.3 billion users monthly. The
platform is loaded 3 billion times daily and processes 70 terabytes of
real-time social data from across the web weekly to power an end-to-end
data-driven product suite.

"The flow of big data for advertisers and publishers is only valuable
if the data becomes actionable," says AddThis CEO Ramsey McGrory.
"AddThis powers the social web and social advertising through
sophisticated data-driven products that make site owners and brands
smarter and more effective."

For site owners, AddThis expands its product set beyond sharing to a
full suite of social plugins. The addition of Follow, Welcome, and
Trending Content plugins and enhanced real-time Analytics will help to
help publishers and advertisers make their sites and content more
personal and engaging for visitors.


  --  Follow Tool - Follow buttons can be placed with content on site to allow
      users to become fans, followers or subscribers in one click.
  --  Trending Content Tool - The Trending Content tool uses a content feed
      API to continuously promote a brand's top content in real time on their
      site, in newsletters or on social channels.
  --  Welcome Tool - The Welcome tool allows publishers to optimize an
      incoming user's experience by welcoming them with a personalized
      greeting and call-to-action.
  --  Additions to Analytics platform - The Analytics product is expanding to
      provide insights on content generating fans and followers and the most
      popular sharing format - copying/pasting a URL.




"Together AddThis Analytics and the Trending Content tool automatically
showcase the content our readers are engaging with most. Trending
Content visually programs the most shared articles, while our editors
log in to AddThis Analytics to get real-time insights into social
performance for creating more of the content our users want," says Ryan
Urtheil, Director of Operations, Parade Magazine.

For brands, AddThis is expanding its social suite to activate data for
paid-owned-earned strategies with their Social+ audience product set,
which serves over 500 brands and their agencies. Social+ audiences
leverage the largest social and interest graph on the web, enabling
advertisers to tap how users are connected by social behavior, brand
affiliation and intent.

"We utilize AddThis data products and services to drive receptive new
1-800-Flowers users into our conversion funnel. For Mother's Day, we
are relying on AddThis' custom modeled audience targeting capabilities
to reach users at significant scale for greater efficiency and ROI
during our biggest holiday period," says Will Ferguson, Senior Director
of Online Marketing, 1-800-Flowers.

"We partner with the AddThis team on social data solutions because
AddThis' audiences provide quality reach we can't get elsewhere," said
Xaxis' Eugene Becker.

As of May 10, 2012, the AddThis, Clearspring Technologies, and XGraph
will consolidate and move forward under the name AddThis. XGraph will
remain a standalone brand for the data technology and processing
platform of AddThis.
