People Data Labs vs Seamless.AI

People Data Labs provides B2B data products for building data-driven products and enriching person and company records. Its APIs can look up person profiles from details such as a name, location, email, phone, education, work history, or social profile; requests need sufficient information to identify a match. The company dataset describes more than 23.8 million global companies, with fields such as name, domain, industry, location, LinkedIn URL, employee count, and founding year. The listed contact database size is 3 billion, and the product includes direct-dial and intent data. API offerings cover person and company enrichment, search, IP enrichment, and person identification. The free plan is free for up to 100 credits per month, but contact data values are obscured. Pro starts at $98 a month, with 350 credits per month as the starting level and contact data included. Enrichment requests typically use one credit per successful request; Search uses one per returned profile.

Seamless.AI is a real-time search engine for B2B lead and contact prospecting, available on web, through an extension, and by API. It searches the public web to find and validate contact information; the listed contact database size is 1,300,000,000. Prospector uses dynamic filters to find verified emails and mobile phones for B2B buyers. Buyer Intent highlights prospects actively buying a product, while Job Changes tracks decision-makers changing jobs. CRM Enrich adds information to CRM records, and outreach features cover email, calls, and social channels, including email sending and an AI-powered phone dialer. The integrations page names Salesforce, HubSpot, Microsoft Dynamics, Outreach, Salesloft, Zoho CRM, and Pipedrive, with availability and capabilities varying by integration and plan. The free plan costs nothing for one user and 50 credits. Pro lists unlimited exports, while Enterprise lists unlimited users and exports; neither plan has a listed price. API key access is available on business plans, with eligibility and pricing details available from sales. The company says it refunds a credit automatically for an invalid email.
