A workspace is a self-contained CRM: its own records, custom fields, members, and billing. Nothing is shared between workspaces, and you can belong to several at once.
Rename it
On Workspace Settings (click your workspace name in the sidebar), the Workspace Name section holds the display name and the Workspace Slug, which is the lowercase identifier in your workspace's URL. Renaming is safe any time; changing the slug changes your URLs, so update any bookmarks.
Run more than one
The workspace switcher at the top of the sidebar lists every workspace you're a member of, and switching is instant. Create Workspace in the same menu starts a short wizard: name it, pick its URL handle, tell Relaticle what you'll use it for, and invite your first teammates, by email or by copying the 7-day join link.
Separate clients, separate businesses, or a sandbox to try things in: each workspace keeps its data, fields, and plan entirely to itself.
Delete it
At the bottom of Workspace Settings, Delete Workspace winds a workspace down with a safety net: deletion is scheduled 30 days out, and the page shows a Cancel Deletion button for the whole grace period. After the 30 days, the workspace and all its records are permanently removed, so export your data first if you'll want it.
Your original personal workspace can't be deleted, and only the workspace owner sees the delete section.
