Tagkast is a service that provides on-site photography at events that allows guests to instantly share photos on social media. This creates a viral marketing effect, with each photo potentially seen by hundreds of the guest's friends. It also allows the business to collect more customer data like emails and Facebook likes. On average, over 50% of guests at an event will participate, sharing photos that create thousands of social media impressions for the business. Tagkast packages start at $799 per month and provide equipment, photography staff, and analytics to measure the results.
