For the first time on the Polish banking market, the legal and operational integration and the rebranding of all branches was successfully completed over one weekend. The bank needed only 72 hours to migrate the data of nearly 400,000 customers and their products to the systems of Santander Bank Polska and change the signage of 113 branches. Over 1,900 persons from both organizations were involved in the merger project. Out of the 2,200 people who joined the bank, 1,700 were employees. Thanks to the transaction, Santander Bank Polska strengthened its position of one of the top financial institutions in Poland.
