# The Brein workspace

> A plain-language map of where to find companies, people, contacts, campaigns, research, and team context in Brein.

Brein keeps the commercial work in one place. Different spaces answer different questions, so a company you found does not silently become a contact or a campaign recipient.

## The spaces you will use

### Find the market

* **Empresas** — search for companies that fit the market your team described.
* **Personas** — review masked public professional profiles inside a company result.
* **Licitaciones** — explore published tenders and the source behind each result.
* **Proveedores** — explore Brein's published supplier sources.
* **Adjudicaciones** — review awards, buyers, suppliers, amounts, currencies, and dates as published.
* **Registros** — review permits and registry information, including the limits of each source.
* **Investigador** — run a deeper research brief and return with a document that can be reviewed and kept.

### Keep the context

* **Cerebro** — save your offer, ideal customer, exclusions, geography, buyer language, playbooks, and team decisions as documents.
* **Configuración** — manage the workspace, team, billing, connections, privacy, and deletion.

### Work the opportunity

* **Personas** are candidates while their contact details remain masked.
* **Contactos** are people whose details have already been revealed or imported.
* **Prospectos** is where your team works with people it has explicitly chosen.
* **Campañas** lets you prepare an email sequence from contacts with an available work email. A draft is not a send.

## One simple rule

```text theme={"theme":"github-light"}
Company or market result → research context
Masked person → candidate
Revealed or imported person → acquired contact
Chosen contact → Prospectos record
Reviewed contact + approved content → Campaign
```

This keeps discovery separate from spending credits and sending messages.
