Vendors sponsor a conference for exposure. I have enlisted Goosechase to get attendees to flock to vendor booths and interact with the vendors that are helping make our conference a success. It is so much fun to see the vendors and participants interact to complete missions. We also got creative in our mission titles and tasks so that the vendor and/or company name was included. And, the winner got the Vendor Social grand prize (donated by the vendors). Past prizes have included drones, Alexa, Swivl, and a Chromebook! Not bad for a bunch of fun!
