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.
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 →
| Metric | Seltz | Standing |

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.
