Best company enrichment API
“Best” is vendor marketing until someone measures it. This is the measured answer: seven company enrichment providers, the same 300 identity-verified companies, judged field by field against LinkedIn-backed reference data. People Data Labs currently returns the most correct data end to end (86.7% correct field yield), while PredictLeads is the most accurate on the fields it returns (88.7%). There is no single best on every axis — accuracy, coverage, speed, and cost favor different tools.
Company enrichment providers, ranked on measured data
Ranked by correct field yield — of the fields that could be filled correctly, how many were. Lower cost and latency are better; higher everything else is better.

Tools people compare that aren't measured — and why
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. Migrating off Clearbit? Clearbit alternatives, measured →
Best enrichment API — common questions
What is the best company enrichment API in 2026?
There is no single best — the independent benchmark splits it by measured axis: People Data Labs returns the most correct data end to end (86.7% correct field yield), PredictLeads is most accurate on the fields it returns (88.7%), and Ocean.io is cheapest at public self-serve rates ($1.92 for the 300-company cohort). Route by the axis your workflow is constrained by.
What is the best company enrichment tool or software for CRM data?
For CRM hygiene the axis that matters is correct field yield — of the fields that could be filled correctly, how many were. Current leader: People Data Labs at 86.7%. If your concern is wrong values overwriting good data, rank by accuracy when present instead: PredictLeads at 88.7%.
Which company enrichment vendor is cheapest?
Ocean.io at $1.92 for the full 300-company cohort, using each vendor's entry paid self-serve rate (free allowances and volume discounts excluded; Apollo and Explorium use recorded usage proxies). Cheapest is not best — check yield and accuracy beside cost.
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. For measured Clearbit replacements, see the Clearbit alternatives page.
How is 'best' measured here?
Seven providers receive the same 300 identity-verified company domains; responses are normalized to one seven-field contract (name, domain, HQ, founded year, industry, LinkedIn URL, headcount band) and judged field-by-field by GPT-5.6 against LinkedIn-backed reference data. No vendor pays for inclusion or rank; inputs, outputs, and judgments are public and reproducible.
