Youbba is a startup founded in 2013 by three students focused on mobile apps for hospitality and retail. Their first app, James, is a mobile butler app for hotels and bars that allows customers to order directly from their mobile devices. The presentation outlines James' features for both customers and business owners, including ordering functionality, real-time reporting and analytics, and marketing capabilities.
