Our humble beginnings, like most, began with an idea. The idea that publishers and advertisers deserved more. With over 30 years of experience in communications technology, and having lived and survived the “dotcom burst”, we were equipped with the wisdom to help address industry concerns in a new and exciting way.

We took our knowledge gained from years of experience, combined it with a passion for innovation and customization, and molded it into a solution. A solution for publishers who were looking for more control, "real-time" data and higher returns. A solution for advertisers who were looking for quality media, more campaign insights and a greater ROI. Our business was founded on years of doing what it takes to get the job done right (the first time) and we have been doing it ever since.

Today, we're proud to offer a powerful suite of technology solutions for publishers and advertisers to get the most out of their online advertising. Staying true to our heritage, our solutions are powerful, effective, simple and always improving.
