Systems and methods for consumer participation in a marketing survey and for development of marketing solicitations by corporate clients based on consumer transactional/demographic data are described. An individual seeking to participate in a marketing survey may first choose to be included in a database containing many surveys that have been added by corporate sponsors. The system may select a willing consumer for participation in the survey based on predefined preferred data metrics. Upon participation, the consumer may also receive a reward in the form of a cash payment or gift, which the system may credit directly to the consumer's bank account and/or to the consumer's account with a corporate affiliate. In addition, the platform may be used to generate marketing contact lists based on consumer demographic and transactional data for a corporate client.
