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

Seltz's similar-companies — or "lookalike" — API finds companies that resemble a seed account using companies-scope search from a vendor-submitted natural-language query. Here is how it actually scored on the independent Openbenchmarks lookalike benchmark, and the Seltz alternatives.

\[01\] Seltz on the benchmark

## How Seltz 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 | Seltz | Standing |
| --- | --- | --- |
| Precision@10 (top-of-list quality) | **84.4%** | #3 of 10 |
| Precision@100 (long-list quality, headline) | **63.4%** | #2 of 7 |
| Relevant companies returned | **3,044** | #2 of 10 |

\[02\] how it works

## How Seltz finds similar companies

Seltz surfaces lookalikes via companies-scope search from a vendor-submitted natural-language query. 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 Seltz from an agent

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