# Companies and enrichment

> Company data for your contacts, and filling in what's missing.

## Companies

**Contacts > Companies** lists the companies of your contacts (Kerux links contacts to companies by name). Open a company to see its profile, size, location, market and technology, its **Contacts**, and where each value came from.

Company data works in messages too: `{{company.industry}}`, `{{company.website}}`... The [Variables reference](/help/campaigns/variables-reference.md) lists every company variable.

## Enrichment

Enrichment fills in missing emails, phones and company data. Providers are tried in order until the data is found, and **what you typed is never replaced**.

**1. Add a provider**

Each provider uses your own account and API key: add it in **Integrations > Connections**.

**2. Set the order**

In **Contacts > Enrichment**, tick the providers to use and put them in order. Click **Save order**.

**3. Enrich**

Tick contacts in **Database** and choose **Enrich**, or use **Enrich** on a contact page (under the **Contacts** menu on the left) or a company's page. **Recent enrichments** shows what was filled and which providers were tried.

> [!NOTE]
>
> **Test data (simulated)** fills fake values on `.example` domains, only for trying things out.
