Different tools for different jobs

FullContact is built for cross-channel identity resolution and b2c data enrichment. FullContact is an identity resolution platform that aggregates customer data from multiple sources to create unified profiles across digital touchpoints.

Apollo.io serves a different 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

Both FullContact ($200–$1,000/month) and Apollo.io (Free tier + from $49/month) are in a similar pricing tier.

20–30% of B2B contacts change roles every year. Neither FullContact 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 FullContact 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.
