Best company enrichment providers
The company enrichment vendor landscape splits into two groups: API providers you can measure head-to-head on identical inputs, and gated platformswhose enrichment can't be isolated or self-served. This page maps both — measured numbers for the first group (current leaders: People Data Labs on correct data end to end, PredictLeads on accuracy when present), and the honest reason each vendor in the second group isn't ranked.

Vendors buyers compare that can't be measured — and why
| Vendor | Why it's not in the head-to-head |
|---|---|
| Clearbit (HubSpot Breeze Intelligence) | Standalone enrichment API sunset after the HubSpot acquisition — new API keys are no longer issued and programmatic enrichment requires a HubSpot contract, so it can't be tested on identical self-serve terms. |
| ZoomInfo | Enrichment gated behind sales/enterprise contracts with no self-serve API. |
| Clay | A workflow platform running waterfall enrichment across multiple providers inside its tables — not a single isolatable enrichment API to score on its own. |

Enrichment providers — common questions
Who are the best company enrichment providers in 2026?
Among providers measurable head-to-head (self-serve API, identical inputs): People Data Labs leads on correct data end to end (86.7% correct field yield), PredictLeads on accuracy of returned fields (88.7%), and Ocean.io is cheapest at self-serve rates ($1.92 for the cohort). Platform vendors — Clearbit/Breeze, ZoomInfo, Clay — are compared by buyers but can't be measured on identical terms; their accuracy is a vendor claim until measured.
Which company enrichment vendor is the most accurate?
Two measured answers: for the most correct data overall, People Data Labs (86.7% yield); for the fewest wrong values among returned fields, PredictLeads (88.7% accuracy when present). Judged field-by-field by GPT-5.6 against identity-verified LinkedIn data on the same 300 companies.
What's the difference between an enrichment provider, tool, and platform?
Mostly packaging: 'provider' or 'vendor' is the company selling the data; 'tool' the self-serve product; 'platform' a broader suite (ZoomInfo, Clay) where enrichment is one feature. The measurable layer is the API — a company domain in, structured firmographics out — which is what this benchmark scores.
Why aren't Clearbit, ZoomInfo, or Clay in the measured ranking?
Clearbit's standalone API is sunset (enrichment now requires a HubSpot/Breeze contract), ZoomInfo's enrichment is sales-gated with no self-serve API, and Clay runs waterfall enrichment across providers inside its tables rather than exposing one scoreable API. The ranking covers providers testable on identical self-serve terms.
