The invention relates to a system and method for providing anonymized, filtered data from a financial institution having cardholders to a business client. The method may include the steps of storing data in at least one database. The data may include credit card transaction data and debit card transaction data maintained by the financial institution, cardholder demographic data maintained by the financial institution, and other data maintained by the business client. The method may also implement a heuristic process to clean the data. Further, the method may comprise providing an interface for the business client to allow the business client to filter and display the data. The interface can anonymize the data to safeguard the privacy of the cardholders, receive input from the business client as to desired filtering criteria, wherein the filtering criteria include time period, geographic region, type of merchant, and cardholder demographic data, and present the anonymized, filtered data to the business client. The invention can thus enable improved decision making by the business client in various promotions, investments and other transactions.
