+Company Segments
+################
+
+.. vale on
+
+Company Segments group Companies based on shared attributes or criteria, enabling targeted Account-Based Marketing - ABM - strategies. Use Company Segments to organize Companies for Campaign targeting, reporting, and bulk operations.
+
+.. note::
+
+   Company Segments are distinct from Contact Segments. While Contact Segments group individual Contacts, Company Segments group entire Companies. This lets you target organizations rather than individuals in your marketing automation.
+
+.. vale off
+
+Creating a Company Segment
+**************************
+
+.. vale on
+
+#. Navigate to **Companies > Company Segments** in the menu.
+#. Click the **New** button to create a new Company Segment.
+#. In the **Details** tab, configure the following:
+
+   * **Name** - The internal name for your Company Segment.
+   * **Public name** - An optional alternate name visible in certain interfaces.
+   * **Description** - A description of the Segment's purpose.
+   * **Active** - Toggle to make the Segment available for use. Inactive Segments aren't available as Campaign sources or in other areas of Mautic.
+
+.. vale off
+
+Company Segment filters
+***********************
+
+.. vale on
+
+Use filters to create dynamic Company Segments that automatically include or exclude Companies based on field values. Mautic evaluates Companies against these filters during Segment rebuilds and updates membership accordingly.
+
+Configuring filters
+===================
+
+#. In the Company Segment editor, click the **Filters** tab.
+#. Select a Company field from the dropdown to filter by.
+#. Choose an operator and specify the filter value.
+#. Add additional filters using **And** or **Or** logic:
+
+   * **And** - Companies must match all connected filters.
+   * **Or** - Creates a new filter group that includes Companies matching any group.
+
+#. Click **Save and close** to save the Segment.
+
+Available filter operators
+==========================
+
+The available operators depend on the field type:
+
+* **Equals / Not equal** - Exact match or exclusion of a value.
+* **Empty / Not empty** - Whether the field has a value.
+* **Like / Not like** - Partial string matching with wildcards.
+* **Contains / Starts with / Ends with** - String position matching.
+* **Greater than / Less than** - Numeric or date comparisons.
+* **Regexp / Not regexp** - Regular expression pattern matching.
+
+.. note::
+
+   Companies automatically move into or out of dynamic Segments when their field values change and the Segment Cron job runs. See :ref:`Company Segment Cron job<Company Segment Cron job>` for configuration details.
+
+.. vale off
+
+Static Company Segments
+***********************
+
+.. vale on
+
+Static Company Segments don't use filters. Instead, you manually manage membership through the methods below.
+
+.. vale off

+
+Viewing Company Segment membership
+**********************************
+
+.. vale on

+
+To view Companies in a Segment:
+
+#. Navigate to **Companies > Company Segments**.
+#. Click the Company count link for the Segment you want to view.
+
+This opens the Company list filtered to show only Companies in that Segment.
+
+.. vale off
+
+Searching Companies by Segment
+******************************
+
+.. vale on
+
+Filter the Company list by Segment membership using the search syntax:
+
+.. code-block::
+
+   segment:{segment-alias}
+
+Replace ``{segment-alias}`` with the alias of your Company Segment. Mautic generates the alias automatically from the Segment name, but you can also set it manually.
+
+.. vale off
+

+
+Editing a Company Segment
+=========================
+
+.. vale on
+

+
+Activating and deactivating
+===========================
+
+Make a Segment active or inactive to control whether it's available for use:
+
+#. In the Company Segment list, click the colored status indicator - green when active, red when inactive.
+#. You can also edit the Segment and toggle the **Active** setting.
+
+Inactive Segments aren't available in Campaigns or other features.
+
+.. vale off
+

+=========================
+
+.. vale on

+
+Run this command regularly, for example every 15 minutes, staggered with other Cron jobs to distribute server load.
