140Proof is an ad platform for Twitter featuring Personalized Ads for Twitter's 150 Million Users. Most ad solutions sell you keywords because they can’t deliver measurable engagement or real human interaction. 140 Proof™ can. 140 Proof lets you see consumers through the lens of Twitter. We match ads to people by what they care about, using public Twitter data. Ads that succeed are retweeted and shared with followers. You pay only for your “first-order” audience; succeeding reach via retweets and word of mouth is both free and quantifiable. 140 Proof’s patent-pending algorithm reaches the right audience across mobile devices, desktop clients, and the web: wherever tweets are served.
