ZoomInfo is built for enterprise b2b intelligence with org charts and technographics. ZoomInfo is the enterprise B2B intelligence leader with 300M+ profiles, org charts, technographics, and buying intent, used by large sales and marketing teams.

20–30% of B2B contacts change roles every year. Neither ZoomInfo nor Apollo.io is designed to continuously monitor your existing CRM for job changes and update records automatically — that's a different tool category.
🇪🇺 GDPR and data compliance
Neither ZoomInfo nor Apollo.io has a particularly strong GDPR documentation posture — both rely on US infrastructure.
For European teams or those with EU customers requiring documented sub-processor chains, the compliance posture of your enrichment vendor matters. Make sure to request a DPA and sub-processor list before committing.
