Both are prospecting database tools — but with key differences

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.

Apollo.io serves a similar purpose: outbound prospecting and email sequences. Apollo.io is a B2B sales intelligence platform combining a 275M+ contact database with email sequencing, AI prospecting, and CRM integrations.

💶 Pricing comparison

Apollo.io (Free tier + from $49/month) is priced lower than ZoomInfo at $15,000–$30,000+/year.

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.

Neither fits perfectly? A third option worth knowing
