Careers at Rubicon Project


Rubicon Project’s mission is to keep the Internet free and open and fuel its growth by making it easy and safe to buy and sell advertising.

Founding story

Frank Addante, Duc Chau, Craig Roah, and Julie Mattern had all worked together at online ad network L90. Addante had been monitoring the industry closely and realized two things. One, that websites did not have the technology to monetize their advertising inventory. Two, that there were numerous ad networks (over 150) and advertisers were spending their funds with all of them.

Addante believed this situation made things harder for publishers, who could only utilize so many networks (likely three at most) due to their capacities. This meant they could only reach so much of the market. So he decided to create a solution enabling them to automatically target the networks that were most relevant based on factors such as demographics, geography, and context.

The purpose of the solution would be to ensure that publishers reached the most appropriate audience, helping them to improve their advertising effectiveness. Addante partnered with Chau, Roah, and Mattern to launch a company to develop the product in 2007. Called Rubicon Project, the firm would automate the purchase and sale of ad inventory for buyers and sellers.

In its first few years the company was able to raise significant amounts of funding, including $4 million in a Series A round led by Clearstone Venture Partners in 2007; $15 million in a round led by Mayfield Fund in 2008; and $18 million in a round held in 2010. It used these investments to introduce new capabilities, such as real-time bidding and private marketplace orders.

It also acquired several firms, including Site Scout and Fox Audience Network; OthersOnline, an audience profiling tech firm; and Mobsmith, a mobile tech firm. In 2012 it was named the top-ranked online ad company in terms of reach by Comscore, placing ahead of Google for the first time, as well as AT&T and AOL. In April 2014 it completed an initial public offering and was listed on the NYSE.
