European tech investors take a stake in e-mail marketing firm Silverpop

ATLANTA, Ga. — E-marketing firm Silverpop, which is run by Raleigh native Bill Nussey, has new investors – from Europe.

The Atlanta-based firm closed on $15 million in March and last week added an undisclosed amount from Germany-based European Founders Firm.

The deal was disclosed in a U.K. publication Marketing Direct.

Three brothers – Marc, Alexander and Oliver Samwer – made the investment. They also have put into Facebook and LinkedIn.

"We believe that Silverpop's high-ROI solutions, experienced management team and healthy financials uniquely position the company to thrive in even the toughest economies," said Oliver Samwer in a statement.

Silverpop has grown to more than employees and has several offices around the world.

Given the tough economic climate, the funding “is proof of the value we are providing,” Silverpop’s Will Schnabel, vice president of international markets, told Marketing Direct.
