RainKing

Marketing · Bethesda, United States · Founded 2007

RainKing, established in 2007 by co-founder Bill Kapner, operated as a specialized sales intelligence platform targeting the technology and marketing sectors. The firm provided a Software-as-a-Service (SaaS) solution designed to equip sales and marketing teams with actionable data to identify and engage potential customers. The core of RainKing's offering was a meticulously curated database containing detailed profiles of nearly one million IT and marketing decision-makers across more than 50,000 mid-to-large-sized organizations. Its business model centered on subscriptions to this platform, granting clients like HP, Dell, IBM, and emerging tech companies such as Tableau and Splunk, access to its rich dataset. A key differentiator was the continuous verification of contact information, which was re-checked every 60 days to ensure accuracy. Furthermore, the platform published over 1,500 daily 'investment signals'—customizable alerts indicating potential buying intent, such as personnel changes or new technology initiatives within a target company. A global research team was responsible for gathering, verifying, and delivering these insights, which included detailed organizational charts and direct contact information for key personnel. This comprehensive approach aimed to provide clients with a significant advantage by pinpointing the precise timing and context for their sales outreach. In a significant milestone for the company, RainKing was acquired by DiscoverOrg in 2017 for over $100 million, a move that combined two major players in the sales and marketing intelligence market. This event ultimately led to the integration of RainKing's assets and its eventual discontinuation as a standalone brand following the merger and subsequent evolution into ZoomInfo.
