ING Group

ING is a Dutch banking group formed in 1991 by the merger of the postal bank NMB Postbank and the insurer Nationale-Nederlanden, and it was among the first large banks to build a direct, branch-light retail model. It serves retail customers in the Netherlands, Belgium, Germany, Poland, Spain and several other markets through mobile-first banking, and runs a substantial wholesale bank covering lending, transaction services and financial markets for corporate clients. Headquartered in Amsterdam and listed on Euronext, the group divested its insurance operations after the financial crisis to focus on banking.
