# Company Universes 101

A **company universe** is a set of companies you select for analysis or export. Universes give you control over *which companies* you want to work with, whether that’s a peer group, an index, or the entire Tracenable coverage. Once created, a universe can be reused across different datasets and workflows, so you don’t need to start from scratch every time.

On the following pages, you’ll find step-by-step guidance for managing universes:

* [**Create a Universe**](/platform/company-universes-101/create-a-new-universe.md) – start fresh from the Universe Panel or the Company Screener.
* [**Add or Remove Companies** ](/platform/company-universes-101/add-remove-companies-to-from-a-universe.md)– adjust your universe composition directly from the screener.
* [**View Companies in a Universe**](/platform/company-universes-101/view-companies-in-a-universe.md) – filter the company screener to see which companies belong to a given universe.
* [**Rename a Universe**](/platform/company-universes-101/rename-a-universe.md) – update the name and description of your universes to keep things organized.
* [**Delete a Universe**](/platform/company-universes-101/delete-a-universe.md) – remove a universe when it’s no longer needed.
