-------------【About the company】-------------
The company is a startup company that provides digitalized services for lending and credit management with the mission of "changing the way of lending, changing the way of borrowing.
In 2017, the company obtained its own money lending license and began offering the first online lending service in Japan. They have pioneered online lending in Japan. In recent years, they have built on the operational expertise of their services to develop their core business of providing online lending platforms for financial institutions and business companies.
The company provides a lending platform that radically improves the productivity of both borrowers and lenders by offering a smooth, paperless UI/UX from the borrower's application to information registration, contract signing, and repayment. To date, the platform has been used by leading Japanese financial institutions such as Mitsubishi UFJ Bank, Mizuho Bank, and Bank of Fukuoka for their online lending services.
As a new business, the company has launched Japan's first digital servicing business, which will "change the way of returning loans". This service enables a drastic digitalization of conventional analog delinquency and reminder services (telephone calls and mailings by operators, etc.).
Going forward, the company plans to grow along two main axes: the "product axis" and the "customer axis. In the former, they plan to provide digital services for more fund-oriented products, such as leases, personal loans, and corporate account openings. In the latter, they will continue to strive to expand the number of beneficiaries by having many financial institutions use the services as a DX partner in the financing area. They have also recently established a local subsidiary in Singapore and plan to expand overseas to Southeast Asia and other regions in the future.
