ZoomInfo

Market leader in B2B contact data and go-to-market intelligence platforms

ZoomInfo is a publicly-traded B2B data and go-to-market intelligence platform that provides comprehensive business contact information, company intelligence, and sales and marketing automation tools. The company operates one of the largest and most accurate databases of business contacts and company information, serving as a critical infrastructure layer for B2B sales and marketing teams. While not a traditional AdTech company, ZoomInfo plays a significant role in the marketing technology ecosystem by enabling account-based marketing, lead generation, and audience targeting capabilities that bridge the gap between data intelligence and marketing execution. ZoomInfo's platform combines proprietary data collection methodologies, AI-powered insights, and workflow automation to help businesses identify ideal customers, understand buying intent, and orchestrate outreach at scale. The company has grown significantly through both organic development and strategic acquisitions, including Chorus.ai (conversation intelligence) and RingLead (data orchestration). With thousands of enterprise customers across various industries, ZoomInfo has established itself as a market leader in the B2B intelligence space, competing directly with platforms like LinkedIn Sales Navigator, Apollo.io, and Cognism.
