We are a company that works to solve the social issues facing the logistics industry. Business-to-business logistics in particular is extremely complex, with diverse stakeholders and structural dynamics. Until now, operations at each site have evolved individually, and we are developing SaaS-type applications that redefine and support these operations through digital transformation (DX).

Our main services include solutions related to logistics processes, such as truck reservation acceptance, dynamics management, vehicle dispatch ordering and management, and production, sales, and inventory management, to support the optimization of business-to-business logistics.
All of these services are built on a common infrastructure, which also stores big data related to logistics. With this common platform, we are promoting the construction of a "logistics information platform" that aims to optimize the entire industry, avoiding inefficiencies caused by individual optimization.

Currently, a large number of companies and logistics providers, mainly in the daily necessities and food industries, have introduced the service, with approximately 27,000 offices nationwide and more than 700,000 drivers using the service.
