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

CUFinder's similar-companies — or "lookalike" — API finds companies that resemble a seed account using company lookalike finder using a name, domain, or LinkedIn URL. Here is how it actually scored on the independent Openbenchmarks lookalike benchmark, and the CUFinder alternatives.

\[01\] CUFinder on the benchmark

## How CUFinder scored

Same B2B seed companies as every other vendor; a three-model LLM judge panel scores each returned company for relevance. [See the full methodology and matrix →](https://openbenchmarks.com/lookalikes) 

| Metric | CUFinder | Standing |
| --- | --- | --- |
| Precision@10 (top-of-list quality) | **38.9%** | #10 of 10 |
| Precision@100 (long-list quality, headline) | **—** | — |
| Relevant companies returned | **183** | #10 of 10 |

\[02\] how it works

## How CUFinder finds similar companies

CUFinder surfaces lookalikes via company lookalike finder using a name, domain, or LinkedIn URL. 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.

## Using CUFinder from an agent

How an agent runs a lookalike / company search on CUFinder — the access model (does the agent get in on its own, or does a human?), the exact call, and the credits.
