Best company enrichment tools
Every enrichment tool claims the best data. None of those claims are comparable — each vendor tests on its own sample. This guide is built the other way around: seven tools, the same 300 identity-verified companies, every field judged against LinkedIn-backed reference data — then you pick by the constraint that actually bites in your workflow, not by an overall score.
The short version: People Data Labs for the most correct data end to end, PredictLeads for the fewest wrong values written, Ocean.io on a budget. The full constraint-by-constraint split is below.
There is no single “best” company enrichment API — the independent benchmark points to a different provider depending on the axis your workflow is constrained by. Every leader below is measured on 300 identity-verified companies:

How to test an enrichment tool on your own data
The benchmark's method is copyable for a buying decision: take 50–100 of yourreal domains — include long-tail, international, subsidiaries, and recent rebrands, because that's where tools diverge — run them through each candidate, and score correct field yield (of the fields that could be filled correctly, how many were), not raw coverage. Returned is not the same as right: a tool can fill every field and still write wrong values into your CRM. Weigh cost at your actual volume beside accuracy — cheap wrong data is expensive.

Enrichment tools — common questions
What is the best company enrichment tool in 2026?
Pick by constraint, not by a single winner: for CRM data you can trust end to end, People Data Labs (86.7% correct field yield); to write the fewest wrong values, PredictLeads (88.7% accuracy when present); on a budget, Ocean.io ($1.92 for the 300-company cohort at self-serve rates). All measured on identical inputs by an independent benchmark.
What is the best company enrichment software for B2B data?
Whether sold as software, a tool, or an API, the measurable layer is the same: a company domain goes in, structured firmographics come out. Seven self-serve products are measured here on 300 identity-verified companies — the leaderboard ranks them by how much of the available data each got right, with accuracy, coverage, speed, and cost beside it.
How do I evaluate a company enrichment tool before buying?
Don't judge on demo accuracy with famous companies — every tool resolves Google. Test on your real traffic shape: long-tail domains, international companies, subsidiaries, and recent rebrands (the cohort here includes all four on purpose). Compare correct field yield rather than raw coverage — returned is not the same as right — and check cost at your actual volume.
What about Clearbit, ZoomInfo, or Clay?
Compared by buyers but not measured here: Clearbit (standalone API sunset after the HubSpot acquisition — enrichment now requires a HubSpot / Breeze Intelligence contract), ZoomInfo (enrichment gated behind sales contracts, no self-serve API), and Clay (waterfall enrichment across multiple providers inside its tables, not a single isolatable API). Treat their accuracy as vendor claims until measured.
