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.

LeadGenius serves a different purpose: custom b2b research combining ai with human researchers. LeadGenius combines AI with a global researcher network to provide custom B2B data and verified sales leads for enterprise sales and marketing programs.

💶 Pricing comparison

Seamless.AI (From $147/month) is significantly more accessible than LeadGenius at $1,000+/month.

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.
