The Project Panel on the Home Dashboard allows you to see all the projects you are associated with, and gives you the ability to create new projects. You can view projects by the projects created by users within your company (i.e. ‘My Company’) or by projects that have been created by other companies and shared with you (i.e. External Companies).
Selecting ‘My Company’ shows all the projects created within your company that you are a part of.
Selecting ‘External Companies’ shows all the projects that were created by an external company and shared with you. For example, if your client created a project and invited you to a review within that project, that project would show up under ‘External Companies’.
