A Little History

Triggit was founded in 2005 to address a simple question: “Why is the process of buying online display advertising so inefficient?” Over the past six years, Triggit’s innovative demand-side platform has consistently pushed the industry forward. Triggit was one of the first companies to leverage real-time bidding exchanges when they appeared in the fall of 2008, and one of the first bidders integrated into the Google AdX Exchange in the summer of 2009.

Today, Triggit continues to be the most technologically advanced DSP in the market, pushing the envelope in areas ranging from integrated data management through its own DMP, to the development of built-in campaign attribution technology that gives advertisers the first truly accurate measure of overall display media ROI. With access to over 10 billion impressions a day from millions of sites across the web, Triggit uses advanced algorithmic calculations to optimize impression-based pricing and bidding, executing real time buying decisions in less than 50 milliseconds.
