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

PredictLeads's similar-companies — or "lookalike" — API finds companies that resemble a seed account using similar companies via shared tech / news / jobs co-signals. Here is how it actually scored on the independent Openbenchmarks lookalike benchmark, and the PredictLeads alternatives.

\[01\] PredictLeads on the benchmark

## How PredictLeads 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 | PredictLeads | Standing |
| --- | --- | --- |
| Precision@10 (top-of-list quality) | **89.8%** | #2 of 10 |
| Precision@100 (long-list quality, headline) | **—** | — |
| Relevant companies returned | **931** | #8 of 10 |

\[02\] how it works

## How PredictLeads finds similar companies

PredictLeads surfaces lookalikes via similar companies via shared tech / news / jobs co-signals. 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 PredictLeads from an agent

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