Aiwip is a company that provides free printing to UK university students by partnering with sponsors to share messages through their app and printers. They aim to remove the £364 annual cost of printing that students face. Students value the help, saving money that would otherwise be spent on printing. Aiwip has grown its network to over 40 printers enabled across iOS and Android apps, reaching over 421,000 students and serving over 1 million messages. Case studies show sponsors are pleased with the results, such as Diageo who impressed 59,307 students and saved them £11,861 in printing costs through Aiwip.
