Different tools for different jobs
Seamless.AI is built for ai-powered contact finding and email verification. Seamless.AI is a B2B sales intelligence platform using AI to provide real-time contact data, verified emails, and direct dials for sales teams.
FullContact serves a different purpose: 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.
💶 Pricing comparison
Both Seamless.AI (From $147/month) and FullContact ($200–$1,000/month) are in a similar pricing tier.
20–30% of B2B contacts change roles every year. Neither Seamless.AI nor FullContact 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 Seamless.AI nor FullContact 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.
