"Clearspring is the leader in this space, and we look forward to working with the company as it expands its platform and extends its reach into global markets."

Weller will join the Clearspring Board of Directors, joining, among others, Internet pioneers Steve Case, Ted Leonsis and Miles Gilburne.

A growing list of world-class customers, incredible growth in the usage of its syndication services, and a significant investment from a firm with NEA's reputation provide validation that we're leading the charge into the next evolution of the Web," said Leonsis. "We're thrilled that Harry Weller and Nigel Morris have joined the board. Harry brings a proven history of guiding early stage companies to success, and Nigel, who while at Capital One unlocked the market value of their data, brings experience that will help us leverage our vast amount of data to deliver the best end-user experience and the most efficient advertising network on the Social Web."
