Parallel similar-companies API (lookalikes), independently benchmarked
Parallel's similar-companies — or "lookalike" — API finds companies that resemble a seed account using agentic entity search from the same seed-anchored query as Exa. Here is how it actually scored on the independent Openbenchmarks lookalike benchmark, and the Parallel alternatives.
How Parallel 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 | Parallel | Standing |
|---|---|---|
| Precision@10 (top-of-list quality) | 69.2% | #6 of 9 |
| Precision@100 (long-list quality, headline) | 56.9% | #4 of 6 |
| Relevant companies returned | 2,675 | #4 of 9 |
How Parallel finds similar companies
Parallel surfaces lookalikes via agentic entity search from the same seed-anchored query as Exa. 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 Parallel from an agent
How an agent runs a lookalike / company search on Parallel — the access model (does the agent get in on its own, or does a human?), the exact call, and the credits.
