Patent number: 10310797Abstract: An electronic platform is disclosed that helps extend the lifespan of relationships, for example, between a salesperson and their client. The platform allows the user to have an account in which the user can store content which may be provided to a second user in an exclusive session through a generated unique URL. The platform is configured to selectively share only what one user wants to a particular recipient. A user interface connected through the unique URL is only accessible by the two users. The interface may provide each user with a section of the display from which to interact with the other user by using selectable features that are shared by both users on the interface. A duality of use is achieved through two-way communication through the page of the interface which helps build the relationship by each side providing feedback to the other side.Type: GrantFiled: October 27, 2016Date of Patent: June 4, 2019Inventor: Steve Mark Rayner
