A system and method for enabling identification of and engagement with, high-value participants within the venue of a live-event from data collected and saved at events for providing improved customer service, marketing of products and increasing ticket sales to events are disclosed. An on-site wireless captive portal technology is used to authenticate attendees to live-events, and, upon authentication, collect their personal preferences and social profile details in real-time. The information collected at the live event is used to update a historic database at a main server station. The data stored in the historic database is analyzed to identify high-value participants of live events and their preferences, to provide them improved customer service, and focused marketing and sales incentives at live-events, thereby improving the live event experience of each of these attendees, while improving ticket sales.
