Best company enrichment API for US companies
Apollo leads this reviewed slice on enrichment success at 87.5%. The result covers 109 companies and 510 eligible field judgments—not vendor-reported geographic coverage.
This slice tests enrichment on US-headquartered companies without mixing the result with international coverage. It is useful for domestic CRM enrichment, territory routing, segmentation, and account research.
Correct company data for US companies, field by field.
Rows are ranked by enrichment success rate: correct values divided by all eligible human-reviewed values. The five field columns reveal where that aggregate comes from. Missing and incorrect values both lower the score; unavailable Ground Truth is excluded.

The overall leader and field leaders answer different questions.
Use overall yield for broad CRM enrichment. For a narrow workflow, route on the field actually written downstream rather than assuming the aggregate winner leads every column.
Scope guardrail: US membership is based on reviewed headquarters, not incorporation, customer footprint, provider output, or a vendor coverage claim.

One benchmark, filtered by reviewed headquarters.
Geography is assigned from human-reviewed HQ Ground Truth before provider results are aggregated. Provider output never decides whether a company enters this slice. Every API receives the same company-domain input, responses are normalized to the same field contract, and the same five field judgments power both this page and the global table.

Which company enrichment API performs best for US companies?
Apollo has the highest measured correct-field yield in this 109-company slice at 87.5% (446/510 eligible human-reviewed field values correct). Field-level leaders can differ, so the table should be matched to the intended workflow.
How are US companies defined?
Companies whose human-reviewed headquarters is in the United States. US membership is based on reviewed headquarters, not incorporation, customer footprint, provider output, or a vendor coverage claim.
Is this a separate benchmark?
No. It is a transparent slice of the same 282-company benchmark. Every provider received the same company-domain inputs, and the same field judgments and scoring rules are used. The main benchmark contains the complete methodology and overall results.
