# Creating segments

## What's a segment?

Segments are reusable lists of companies created based off one of more of the following:

* [Company attributes](/product-handbook/concepts/company.md#attributes)
* Flag access
* Flag metrics
* Feature feedback

Company segments can be used as access rule for managing flag access.

## Getting started <a href="#get-started" id="get-started"></a>

* Go to the `Companies` page on the sidebar
* Click on the `Add filter +` menu item to build your segment conditions

## Set segment conditions

Each segment is created using a set of conditions. You can add as many segmentation conditions as you’d like.

### Conditions

* `Company attribute`

  * `is enabled`
  * `is not enabled`
* `Flag metric`
  * `Track count`
  * `Exposure count`
  * `First track`
  * `Last track`
* `Segment`
  * `in Segment`
  * `not in Segment`
