Silverpop, a leading provider of on-demand marketing technology, has closed a $15 million round of funding. The funds are earmarked for international expansion, R&D acceleration and to fund additional acquisitions to round out the company’s on-demand marketing suite. The D.E. Shaw group’s venture capital unit, a new investor, led the round along with existing investor Draper Fisher Jurvetson and others. Silverpop is the only company that has consistently been named by JupiterResearch as one of the top two enterprise oriented email service providers each of the last four years.

“On-demand marketing solutions are changing how marketers do their jobs. They are able to be more flexible, more responsive and more competitive, all with lower costs,” said Silverpop CEO Bill Nussey. “The demand for Software-as-a-Service marketing solutions is growing at an amazing rate, and investors are beginning to realize the tremendous upside of this market.”

“DFJ has long been an investor in Silverpop’s bright future, and we continue to see strong potential in the online marketing suite of services it offers,” said Andreas Stavropoulos, managing director of Draper Fisher Jurvetson. “Because its management team consistently exhibits a unique ability to identify the essential online tools marketers need and make them better, Silverpop will continue to thrive along with its clients.”
