140 Proof

140 Proof is the first scalable social advertising platform, reaching over 40 million social users with its Relevance Engine powered by the public Interest Graph. 140 Proof’s Relevance API provides primary revenue streams for premium apps and websites like UserSocial, Echofon, Plume, and HootSuite.

The company was founded in 2010 by Jon Elvekrog and John Manoogian III, with Vanessa Naylon, Ryan Matsumura, and Andy Scott. The original idea for 140 Proof sprang from the 2009 social analytics platform Plus One which targeted specific interests in the public social stream.

140 Proof brand ads are 140 character messages (and 140 second videos), targeted based on public interest data to specific demographic “personas”. The ads are full social objects, meaning they can be shared with a click, multiplying the size of the audience and lowering advertisers’ effective costs. Unlike promoted hashtags or promoted tweets, 140 Proof ads are highly targeted based on the public Interest Graph, and reach millions of engaged users.

140 Proof’s API reaches social users on smartphones and the social web, including premium apps on iPhone and Android. Recent customers include brands like Microsoft, Disney, Infiniti, General Motors, Levi’s, Coke, AT&T, Best Buy, and Victoria’s Secret. Key members of 140 Proof Platform include JumpTap, Celtra, and OneLouder.
