Share Washi is a marketplace app built for a community of about 100,000 active users who consistently buy washi tapes to decorate their notebooks.
With hundreds of new washi tape designs coming into market every month, people have started to form a new habit of sharing washi tapes. Instead of buying the whole unit (a roll), people are buying parts of a roll (by meters) and theres many individual organizers who hold group buying and also do sub-packing for group members.
However, theres no software, website or app that serves this need. Currently, an group organizer with a 100 group members usually takes three days to generate orders and not surprisingly with many mistakes.
