GroupEZ is an online platform that facilitates the purchase and sale of sporting event tickets on a group basis and leverages interactive aspects of digital communication and its networking capability. The application can be embedded in a team or venue website to provide a robust digital invitation capability for organizing the attendance of events. The resulting service can be described as a combination of invitation and ticketing applications with the addition of enhanced marketing capability for team and venue hosts. Event hosts have the ability to upsell seating, concessions, or fan experiences with a patent pending proposal process. The application reduces friction by making the transaction less risky for the group leader by enabling split payments.
