140 Proof, a San Francisco, CA-based social stream ad platform for Twitter and Facebook, completed a $2.5m Series B funding round.
The round was led by BlueRun Ventures, with participation from angel investors including Mark Kingdon, former CEO of Organic Inc. They joined Ron Conway’s SV Angel and Peter Thiel’s Founders Fund.
Led by CEO Jon Elvekrog, 140 Proof delivers sharable ads to users above their information feeds from Twitter, Facebook and other socially connected services. The company’s patented technology targets consumers based on whom they follow, keywords used in their social streams and other publicly available keys from their social graph.
140 Proof has sales offices in Detroit and New York.
