Headquartered in Tokyo, SBI Sumishin Net Bank is an “Internet-only” bank established as a joint venture between SBI Holdings and Sumitomo Trust & Banking.

Business need
In Japan, competition in the Internet banking business has been intensifying. In this environment, SBI Sumishin Net Bank, Ltd. aimed to bring to market a broad product lineup in a shorter period than other financial institutions.

Development of a totally new Internet banking platform was characterized by the use of an accounting system application package and a service-oriented architecture (SOA) framework.

A total of approximately 600 billion yen in funds was deposited and 400,000 new accounts were opened after only 18 months since the start of operations. The time required to launch the service was shorter than that required for the development of conventional financial products.
