Spotlight is a company started by two ex Stubhub employees that helps companies achieve a higher ROI and easier ticketing management process for their customer hospitality events.
I would imagine that there must be a component that allows companies to sell tickets cheaply if they will not be used for a customer hospitality event. At my company there is always a scramble when customers bail on planned hospitality events. We use leftover or abandoned tickets for recognition purposes with employees rather than trying to sell them through a secondary market.
