People Data Labs vs Perfectly

Summary

People Data Labs is a developer-first API that gives you raw access to 3 billion person records. You integrate it into your own tools, CRM, or ATS to enrich profiles, build custom sourcing engines, or power analytics dashboards. It's infrastructure, not a finished product. You need engineers or technical recruiters who can write queries, handle JSON responses, and build workflows on top of structured data. Pricing is usage-based and scales with API calls. Perfectly is a managed recruiting service that happens to use AI. They're an agency with software layered on top: you describe the role, they deliver vetted candidates using their AI tooling behind the scenes. You don't touch the tech stack. The pitch is speed and volume (10x candidates, 4x faster) without adding headcount. Both claim AI-powered search and data enrichment, but People Data Labs sells you the raw materials while Perfectly sells you the finished candidates. The 6.3 rating and near-identical feature lists suggest both are relatively new or niche, with Perfectly's 12 reviews pointing to very early traction as a YC W26 company. The real decision is build versus buy. If you have technical resources and want proprietary sourcing workflows, People Data Labs gives you control and cost efficiency at scale. If you need candidate delivery without the engineering lift or want to test high-volume sourcing before committing to internal tools, Perfectly removes the implementation burden but locks you into their process and likely higher per-hire costs.
