DiscoverOrg

Was a top-tier B2B sales intelligence provider known for best-in-class data accuracy before merging with ZoomInfo to form the market leader in go-to-market intelligence

DiscoverOrg was a pioneering B2B sales intelligence and data platform founded in 2007 in Vancouver, Washington. The company built its reputation on providing exceptionally accurate, human-verified contact and organizational data — including direct-dial phone numbers, email addresses, org charts, and technographic information — targeting IT, finance, marketing, and other key buying centers within enterprise organizations. Unlike competitors that relied solely on automated data collection, DiscoverOrg employed a team of researchers to verify and refresh its data on a regular cycle, resulting in industry-leading accuracy rates that became a core differentiator. The platform served sales, marketing, and recruiting professionals by enabling them to identify the right decision-makers, understand organizational structures, and prioritize outreach based on intent signals and buying triggers. DiscoverOrg grew rapidly through organic expansion and a series of strategic acquisitions, including the purchase of RainKing in 2017, which significantly expanded its data coverage across additional verticals and geographies. The company became one of the most recognized names in the sales intelligence space, earning consistent recognition on the Inc. 5000 and Deloitte Fast 500 lists. In 2019, DiscoverOrg acquired ZoomInfo and subsequently rebranded the combined entity under the ZoomInfo name, which went on to complete a landmark IPO in June 2020 — one of the largest SaaS IPOs of that year. The DiscoverOrg brand was retired as ZoomInfo became the unified platform, combining DiscoverOrg's data accuracy strengths with ZoomInfo's broader contact database to create a dominant force in the go-to-market intelligence market.
