About

What is People Data Labs

People Data Labs exposes a dataset of 1.5 billion person profiles and millions of company records through a REST API, letting teams enrich contacts, resolve identities, and build targeted audiences without manual research. It's built for SDRs, BDRs, GTM engineers, and RevOps practitioners at SMBs and mid-market companies who need reliable data infrastructure rather than a point-and-click prospecting UI. The standout capability is IP-to-company matching — drop an anonymous IP address in, get a company back — which opens up intent-adjacent use cases most enrichment tools don't touch. Audience building supports filtering across 140+ attributes, covering firmographic, demographic, and social data in a single query. The honest limitation: PDL is a data layer, not a workflow tool — there's no built-in sequencing, CRM sync, or outreach surface, so you'll need to wire it into your own stack.

Our verdict

Vanderbuild take

We think of People Data Labs as the data infrastructure layer for GTM teams who've outgrown copy-paste enrichment — it's the right call for GTM engineers and RevOps practitioners who want to own their enrichment pipeline rather than rent a black-box tool. The REST API is well-documented and genuinely capable, so you can wrap it into your own MCP layer or plug it into an agentic workflow without much friction — no native MCP server confirmed yet, but the API surface is clean enough to build on. Pricing starts free and the Pro tier runs around $98/month, which is accessible for small teams, though costs scale with volume and premium fields are add-ons that can push the bill up faster than expected. The core limitation to flag: PDL is purely a data provider — it has no sequencing, no CRM-native push, and no outreach tooling, so budget time to integrate it before your SDRs see any value.
