People Data Labs vs TargetWise

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.

TargetWise enriches contact and company data and offers reverse-email lookup through REST API and MCP access. Its contact waterfall checks more than 15 specialist sources for requested work-email or business-phone fields, then returns a normalized result. Responses distinguish returned fields from unresolved ones and include source provenance and retrieval time; only successful results consume credits. Company enrichment accepts identifiers such as a website, LinkedIn page, registration or VAT number, or ticker, and returns available profile data one company at a time. Unavailable company fields remain unresolved rather than being guessed. TargetWise provides implementation guides for HubSpot, Salesforce, and n8n, plus an AI-client guide for Cursor and Claude Code. The maker describes workflows in sales, marketing, HR, market research, CRM data quality, embedded products, and AI products. Contact coverage varies with geography, role, source availability, and supplied identifying context. The Free plan includes 20 work emails and five business-phone results. The Core plan costs $49 a month, with a 49 USD monthly usage balance included.
