Fuze uses two main categories that represent people. 

First we have Users - those that interact with the Fuze dashboard and database in order to keep track of particular individuals with whom they are following up. Users are often the leaders of your organization who are assigned to follow-up with outside individuals. Users can only be added by an administrator or another user with permission to do so. Every user has unique login information and is able to interact with the Fuze system based on permissions set by their organization's administrator.

Then we have Contacts - those individuals outside your particular organization with whom you are interested in following up. Contacts each have their own profile page where all of their personal information and follow-up status is stored. They can be assigned to users by administrators or any other user with permission to do so. Information about all of the contacts within one organization is also compiled into helpful analytics.
