Hassan Baydoun of Cashbury.com, the Winner of Arabnet 2011's Startup Demo, describes how he formed the idea while receiving loyalty cards at a coffeeshop, and then developed it at YallaStartup Weekend.

Cashbury, a loyalty card and payment gateway mobile app that is also a social network, is now being piloted in Beirut and San Francisco. Baydoun also shares how having customer feedback from the outset was a critical factor for their success.
