Originally founded in 1965 as "Bank für Sparanlagen und Vermögensbildung AG," the company became known as DiBa (Direktbank-Anlage) and was acquired by the Dutch ING Group in 2004, subsequently being renamed ING-DiBa. It operates as a direct bank, meaning it has no physical branch network, and serves over 9 million customers primarily online and by phone. Its mission is to provide simple, transparent, and affordable financial products, including current accounts, savings accounts, consumer loans, mortgages, and securities brokerage services.
