Rubicon Updates S-1 With Q4 Results, VivaKi Spend Data by Zach Rodgers // Tuesday, March 4th, 2014 – 5:55 pm. An updated S-1 from IPO aspirant Rubicon Project shows the sell-side platform's revenue grew 47 percent in 2013, to $83.8 million for the full year. In its earlier filing, submitted to the U.S. Securities and Exchange Commission (SEC) last month, the company disclosed revenues only up to the third quarter of 2013. The new document shows Rubicon's Q4 revenues were about $28.1 million. Also new in today's S-1, Rubicon gave specifics on what Publicis Groupe's VivaKi digital trading unit spent on the platform. It said, "Vivaki’s total spend on our platform grew approximately 60% from September 2012 to September 2013, with its direct order buying activity growing 750%, to make up approximately 20% of its total buying activity on our platform. Vivaki’s activity on our platform has grown to include buying inventory for 350 advertiser brands, across almost 5,000 websites." VivaKi clients include American Express, Chase, Coke, and eTrade. According to its earlier filing in February, Rubicon saw revenues of $55.7 million for the first nine months of 2013, up 48 percent from $37.6 million it reported for the same period in 2012. The new Q4 data suggests growth in that quarter about on par with the first nine months of the year. The above numbers are net revenue figures, sometimes referred to as revenue ex-traffic acquisition costs. Total revenue managed on the Rubicon platform in 2013 was $485.1 million, a 43% increase over 2012 ($338.9 million). John Ebbert contributed. Add a comment Click here to cancel reply.
