ZoomInfo similar-companies API (lookalikes), independently benchmarked
ZoomInfo's similar-companies — or "lookalike" — API finds companies that resemble a seed account using similar-companies lookup over the ZoomInfo company graph. Here is how it actually scored on the independent Openbenchmarks lookalike benchmark, and the ZoomInfo alternatives.
How ZoomInfo 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 →

How ZoomInfo finds similar companies
ZoomInfo surfaces lookalikes via similar-companies lookup over the ZoomInfo company graph. 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 ZoomInfo from an agent
How an agent runs a lookalike / company search on ZoomInfo — the access model (does the agent get in on its own, or does a human?), the exact call, and the credits.
