Vancouver, WA-based marketing technology firm DiscoverOrg  is acquiring business contact software Waltham, MA-based company ZoomInfo. The deal aims to combine the business and personnel intelligence that both the companies bring into a single dataset, adding value to enterprise marketing tools.

ZoomInfo had been bought over by Great Hill Partners, a Boston-based private equity firm in August 2017. The details of this deal were not disclosed. But close sources have put the figure at more than $500 million.

Together, the two companies will have 1,050 employees. DiscoverOrg founder and CEO Henry Schuck, will lead the combined company. The new business entity will have 15,000 customers and 120,000 active users across the globe, according to a press release.

Founded in 2000, ZoomInfo has developed a database of 100 million global business contacts   DiscoverOrg, founded in 2006, has databases and company intelligence products that marketing teams can use to track companies.

Speaking to ZoomInfo employees at its new headquarters in Waltham, Schuck said the companies will continue business as usual for the next six to nine months as executives decide how to best stitch the two together. Last month, ZoomInfo said it had nearly doubled its headcount since July 2018 to its current 450 employees globally.
