# Company Lookalikes

`POST /v3/companies/lookalike`

Find companies similar to a set of seed companies using AI-powered recommendations.

Provide 5-100 seed companies via domains or LinkedIn URLs. The API returns companies with similar size, industry, and profile.

**Pagination without duplicates:**
On your first request, omit `dedupeSessionId` — the server generates one and returns it. Pass it on every subsequent request to get more results without repeating companies already seen. Sessions are retained for 30 days.

Use the `exclude` field to always filter out specific companies (e.g. existing customers or competitors).

Results are lightweight previews. Use Enrich Companies with the returned `id` to get full firmographic data.

> **Billing:** Charged per result via the `lookalikeCompany` action.

> **Persisting to a table:** Pass `tableId` to also persist matching results into an existing table. See [Companies Tables](#tag/Companies-Tables).
