Santa Barbara-based RingRevenue has raised $3.25 million in fresh venture capital in a round led by investors GRP Partners and Rincon Venture Partners, bringing its total funding to date to more than $10 million.

The company, founded in 2007, initially built a technology platform to let digital advertisers track sales calls the way they track clicks. RingRevenue has inked deals with major advertising networks at Google and ValueClick, but large advertisers have been coming directly to the company to use its platform to automate and track their call-based marketing campaigns.

CEO Jason Spievak said the new capital will be used to make hires across the firm and improve the company’s products. The company has 33 people now and expects to have more than 50 by early next year, with most of the hires in the Santa Barbara area.

“We’re really stepping on the gas now to scale,” CEO Jason Spievak told the Business Times.

The funding round was led by RingRevenue’s existing investors, Los Angeles-based GRP Partners and Santa Barbara-based Rincon Venture Partners.
