# CompanyEnrich similar-companies API (lookalikes), independently benchmarked

CompanyEnrich's similar-companies — or "lookalike" — API finds companies that resemble a seed account using domain-based similar-company search over the CompanyEnrich company index. Here is how it actually scored on the independent Openbenchmarks lookalike benchmark, and the CompanyEnrich alternatives.

## How CompanyEnrich scored

\[02\] how it works

## How CompanyEnrich finds similar companies

CompanyEnrich surfaces lookalikes via domain-based similar-company search over the CompanyEnrich company index. On this benchmark every vendor receives the same compact input (company name + domain + a one-line description), which matches how an AI agent would query it.
