A company administrator can change the workspace display name from the company settings. Open the main menu, select the correct company, edit its name, and save. Check the company switcher afterward so that you do not leave users working in a similarly named workspace.

The display name labels the Nonli workspace; it does not rename connected social pages, brands, domains, URLs, or content on third-party networks. It also does not automatically change the legal entity printed on invoices. Update the billing information separately when the invoiced entity or address has changed.
If the field is read-only, your role lacks company-administration permission. Ask an existing administrator to make the change. Tell affected users about the new label, especially when they can switch between several companies.
