Overview: In January 2018, at the Global EdTech Startup Awards in London, a Japanese firm came through a field of over 2,000 to claim the top prize. Goichiro Arai's company triumphed with an app designed to help students organize and share their study notes, and even create Q&A exercises. Allowing students to study together independently of teachers, and even helping to close the achievement gap between rich and poor, this cutting-edge tool is ready to carry success in Asia over to the global stage.
