Different tools for different jobs

20–30% of B2B contacts change roles every year. Neither Seamless.AI nor LeadGenius 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
LeadGenius has a stronger GDPR posture — GDPR, CCPA. Seamless.AI claims GDPR compliance but relies 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.
