Mark Torres Joins as SVP of People and Culture to Further Support Company Growth

LOS ANGELES – the Rubicon Project, the online advertising technology company, today welcomes Brian Barnum to the team as Chief Financial Officer and Chief Operating Officer and Mark Torres as Senior Vice President of People and Culture. Barnum will be responsible for the successful implementation and over-achievement of the company’s operating plan. In addition, along with the current leadership team, Barnum will drive strategic execution for providing a real time trading platform for publishers who aim to capture the most revenue and the highest possible price for their inventory. Torres will be tasked with maintaining and growing the company’s innovative culture – ensuring the Rubicon Project continues to attract the brightest and most talented industry veterans and technologists.

“The growth of premium real-time enabled inventory available on REVV exploded in 2011 with number of monthly bids growing from 15 billion to more than 1 trillion and impressions traded growing 60% to now more than 120 billion monthly,” said Frank Addante, CEO and Founder of the Rubicon Project. “We believe this growth is a clear indicator of the massive opportunity for the industry in 2012. Brian’s repeated experience in preparing technology companies for the public markets will be valuable in helping us successfully scale and further our commitment to innovate for the industry.”

Barnum’s experience expands across several successful technology businesses, including Transaction Network Services (NYSE:TNS), Rent.com (NASDAQ:EBAY), Business.com (NASDAQ: DEXO) and Dex One Digital, the interactive division of Dex One Corporation. As the Chief Financial Officer, Barnum took TNS through an IPO and secondary offering. At Rent.com, Barnum prepared the company for an IPO while managing an M&A process that culminated in an acquisition by eBay valued at approximately $415 million. While serving as Chief Operating Officer and Chief Financial Officer at Business.com, Brian prepared the company for the public markets, while orchestrating an acquisition for $350M M&A offer by Dex One Corporation. Later he joined the executive team as the President of Dex One Digital, a division which encompasses all of the digital business lines for the publicly traded Yellow Pages publisher.

“I am extremely excited to be a part of this team. Not many companies have the potential, assets and talent to shape the future of what is fast becoming an enormous industry – but Rubicon does,” said Barnum. “I will be focused on applying my experience in taking companies public and driving a crisp operational execution. I’ll be working with our team to help Rubicon evolve beyond its startup roots and continue to innovate and provide publishers the technology they need to successfully compete in today’s market.”

Also joining the team, Mark Torres comes to the Rubicon Project after nine years with Reed Business Information, the world leading business to business publisher. While at Reed, Torres oversaw the Human Resources function as Corporate Vice President, Human Resources supporting titles such as Variety, Broadcast & Cable, Interior Design and Publishers Weekly. Prior to his tenure at Reed, Torres was Vice President of Human Resources at Ticketmaster and prior to Ticketmaster held senior management Human Resources positions at Sony Pictures Entertainment where he oversaw the Television Division.

“Our team is what makes the Rubicon Project so unique. When we started this company, people and culture were the top priority,” adds Addante. “Growing a motivating culture remains a top priority today. The people of Rubicon are the most integral asset of the company, and therefore I’m excited to have Mark on board to ensure we continue to cultivate a culture that inspires, rewards and attracts the industry’s best innovators.”
