The enterprise B2B intelligence platform with the most accurate contact data

About ZoomInfo

ZoomInfo is the gold standard for B2B contact and company data, with 300M+ professional profiles and the most accurate direct-dial phone numbers in the industry. Its Data-as-a-Service platform covers contact enrichment, company intelligence, buyer intent signals (what companies are researching right now), website visitor identification (WebSights), and org chart mapping. ZoomInfo's intent data — identifying companies actively researching your category — is a genuine competitive advantage for prioritizing outreach. The platform integrates with every major CRM and sales engagement tool. The trade-off is cost: entry-level contracts start at $10,000–15,000/year, making it inaccessible for early-stage companies. Compared to Apollo, ZoomInfo has more accurate mobile numbers and better intent data but costs 10x more. Best for: Series B+ companies with dedicated sales teams who need the highest-quality data for enterprise outreach.
