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.

People Data Labs serves a different purpose: large-scale b2b data api for developers and data teams. People Data Labs is a B2B data provider offering 3B+ professional profiles and 18B+ data points via API for developers, data teams, and enterprise applications.

💶 Pricing comparison

Both Seamless.AI (From $147/month) and People Data Labs (From $98/month (API credits)) are in a similar pricing tier.

20–30% of B2B contacts change roles every year. Neither Seamless.AI nor People Data Labs 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 People Data Labs 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.
