ZoomInfo is a B2B data intelligence platform that enriches sales and marketing data with company and contact information, decision-maker identification, and buying intent signals. It integrates with Salesforce, Microsoft Dynamics, and other CRMs to automatically enrich accounts, contacts, and opportunities. ZoomInfo's data comes from multiple sources: job postings, company filings (SEC), news, web mentions, and crowdsourced updates. The platform helps sales and marketing teams identify and target high-value prospects, avoid outreach to wrong contacts, and time outreach based on buying signals.
