# Field coverage: Company Enrichment

\[01\] result

Parallel leads field coverage at 94.7% 

Of the 11 enrichment providers tested on the Company Enrichment API Benchmark, Parallel scored the highest field coverage: 94.7%, across the same 282 company domains.

\[02\] the benchmark

Every provider receives the same 282 company domains: stable large companies, long-tail companies, subsidiaries and verified rebrands. The HQ location, industry, employee band, founded year and LinkedIn URL each returns are judged against human-reviewed ground truth.

\[03\] how field coverage is measured

Field coverage is the share of the five scored attributes a provider returned a value for, right or wrong. It measures willingness to answer, not correctness. Higher is better.
