RingRevenue, which offers a call performance platform that allows companies to complement their marketing efforts with phone-based campaigns, has raised $4 million more in a round led by led by GRP Partners and Rincon Venture Partners, bringing its total financing to $7.5 million.
Call performance marketing basically extends the tracking, measurement and accountability of online performance marketing to those transactions that occur over the phone.
RingRevenue says it currently boasts more than 25,000 publishers and runs hundreds of call-based campaigns for some 10,000 advertisers across its partner networks. According to its About page, RingRevenue has struck partnerships with online juggernauts like Google, ValueClick, Commission Junction and Rakuten.
The company was initially founded in 2007 by a host of Callwave veterans.
With the additional capital, RingRevenue plans to ramp up product development and improvements, expand its customer development and support teams and ultimately expand its presence outside of the United States.
