About Sumally
Sumally is a Japanese company founded in 2010 by Ken'ichiro Yamamoto. The company operates in the sharing economy and e-commerce sectors, offering a service that redefines personal storage and item management.
Yamamoto, an entrepreneur with a background in web services, aimed to create a platform that would seamlessly connect people's possessions with their digital lives. This vision led to the creation of Sumally, a service that has evolved from a social "want" and "have" list into a comprehensive storage and marketplace solution.
The company's primary offering is "Sumally Pocket," a subscription-based storage service. Clients can send their belongings to a secure warehouse, where each item is photographed and cataloged. This digital inventory is accessible to users through a mobile app, allowing them to view and manage their stored items remotely. The service caters to individuals in urban areas with limited living space, offering a convenient way to declutter their homes.
The business model is twofold. Revenue is generated through monthly subscription fees for storage, with different pricing tiers based on the volume of items stored. Additionally, Sumally operates a marketplace where users can list their stored items for sale. The company takes a commission on each transaction, creating a secondary revenue stream and providing users with an opportunity to monetize their possessions.
