# Companies

A company is a business entity that can be linked to one or more people.

## Company fields

Every company has pre-defined fields shared by every company. We call them [native fields](https://help.folk.app/en/articles/4991006-contact-fields).

* `name`: The name of the company.
* `description`: A short description of the company.
* `emails`: A list of email addresses of the company.
* `phones`: A list of phone numbers of the company.
* `addresses`: A list of addresses of the company.
* `urls`: A list of URLs of the company.
* `groups`: A list of groups associated with the company.
* `createdAt`: The date and time the company was created.
* `createdBy`: The user who created the company.
* `fundingRaised`: The amount of funding raised by the company.
* `lastFundingDate`: The date of the last funding of the company.
* `foundationDate`: The date of the foundation of the company.
* `employeeRange`: The range of employees of the company.
* `industry`: The industry of the company.

The first value in the list of `emails`, `phones`, `addresses` and `urls` fields is the **primary value**. Primary values are used to display the most relevant information about the company in the app, and are used as the default value for the field in some operations.
For instance, when sending a campaign to a company, the primary email address will be used to send the email.

<Info>
  You can also add custom fields to companies, which are additional attributes
  that can be defined in each group. Read more about custom fields in the
  [Custom fields](/core-concepts/custom-fields) section.

## Company relationships

### People

Companies can include one or more people, however the relationship is only available on the people endpoints.

In the app, a company will show only people that have that company as their primary company.
