Dex currently only supports one user. However, there are plans to include the capability for multiple users to log onto the same Dex account. This could for example be used for an EA to manage an account and log notes, set reminders, and add new contacts.
Currently, Dex supports integrations with social media sites such as Facebook, Twitter, LinkedIn, and contacts apps such as iCloud and Google Contacts. In Dex for Teams, integrations with professional tools will be included.
A proposed feature has been to include support for the syncing of email and messages to the Dex platform. This would provide greater visibility over the communications of the team.
