Waltham, MA September 25, 2008 -- ZoomInfo, the most comprehensive source of business information on people and companies, reports exceptional growth in its Sales Intelligence business unit, as companies look for ways to identify and connect with buyers, and find a competitive edge in a challenging environment.

With more than 350 new clients so far this year, ZoomInfo's Sales Intelligence business unit is on pace for an annual growth rate exceeding 150 percent. ZoomInfo provides sales and marketing professionals with specialized search capabilities and the most up to date, relevant information on business people and companies.
