ZoomInfo, a 17-year-old provider of business contact data based in Waltham, has been acquired by a Boston-based private equity firm.
Great Hill Partners' acquisition of ZoomInfo was announced Monday evening. Financial terms of the deal were not disclosed.
Founded in 2000 by Yonatan Stern, ZoomInfo's main software product is its "Growth Acceleration Platform," which gives sales and marketing professionals access to a database of more than 222 million business people and 9.3 million businesses. The company raised a $7 million Series A round led by Venrock in 2004. Other investors included Ascent Venture Partners, Flagship Pioneering and Vulcan Capital.
The company was named to 2016's Inc. 5000 list of fastest-growing private companies in the U.S., having grown revenue over three years by 121 percent to $27.5 million in 2015.
In a statement, Great Hill Partners Managing Director Christopher Gaffney said that the company is "growing very fast while maintaining a high level of profitability, a rare combination that attests to the quality of its products, data, and employees."
"In the evolving market of data driven solutions for sales and marketing, we see a significant growth opportunity for ZoomInfo, and trust that with its current track record, strong product innovation and efficient operations they will continue to dominate the market," added Gaffney, who is joining ZoomInfo's board.
