Special Business Idea Presentation

At the first round of paper screening, we found two groups in different high schools in Tokyo, Ms Ririko Aoki & Ms Yuko Kobayashi and Mr Hideki Iwai, had submitted almost the same idea. To proceed to the second round of video screening, we asked them to form a team and develop a pitch video together. These two teams had no connection except they are high school students and had a similar business idea. However, within 2 weeks, they formed a team called PE² and successfully completed a joint pitch video together.

Unfortunately, PE² did not pass the second round; however, we believe that their attempt embodies a true “collaboration” which is imperative in achieving the SDGs, youth engagement, social entrepreneurship and creating innovation. For this reason, we decided to set a special slot during the contest and will showcase the presentation of PE² to the audience. Please come and see a true youth collaboration!
