140 Proof brings precision to in-app advertising by analyzing the billions of signals that run through social platforms.

Brand advertisers and media companies trust 140 Proof to deliver powerful targeted in-app advertising at scale. Top apps and publishers entrust 140 Proof’s high performing ads to bolster their revenue streams.


We believe the most accurate signals of a person’s wide range of interests come from their social data. Each of their social accounts tells a different story. The only way to understand a complete, three-dimensional view of what someone cares about is to look at them all.

Born from great technology.

140 Proof was founded by industry veterans with a passion for data and technology. We invented the Blended Interest Graph, which interprets a wide range of social data, giving brand advertisers the power to go beyond demographics and lookalike models in order to deliver the perfect ad in mobile apps. The earliest applications of our Blended Interest Graph technology placed the first targeted ads into social reader apps.

Solving big problems.

In 2014, as logging in to apps via social ID became the de facto standard, we expanded our network into hundreds of mobile apps in a wide range of categories. Our goal was to solve the biggest problem in mobile app advertising: the lack of quality targeting for brands. Today, many of the world’s most successful brands partner with 140 Proof to do just that.
