Company description

the Rubicon Project is a group of industry-experienced, aggressive and passionate renegades dedicated to bringing a new level of efficiency to the fragmented Internet advertising space. As of January 2008, the company has raised $21 million in funding.

The founders of the Rubicon Project shook up the online advertising industry in 1998 when they created L90/adMonitor, one of the most successful Internet advertising platforms that served over 3,000 of the web’s most recognized sites, reaching 65% of the Internet population before DoubleClick acquired it.


$27 Billion was spent advertising online in 2007, yet it’s still too hard for websites to sell their ad space online. While Internet advertising is an explosive market, it is an incredibly inefficient one with advertisers spending money with 300+ disparate advertising networks worldwide (e.g. Google AdSense, Yahoo! Publisher Network, HispanoClick and Adtegrity). the Rubicon Project’s web-based, self-serve solution gives any size website the most complete access to the total available advertising market and its smart matching technology does all the work to perfectly match each ad impression with the optimal money-making opportunity. the Rubicon Project is the new online advertising standard that makes it effortless for websites to generate the mad cash they've always dreamed of. And, it’s free to join.
