SparkBase, LLC (SparkBase or SB) was a stored-value and gift card transaction processor located in Cleveland, Ohio, United States from 2004 to 2016. It provided private-label, stored-value, specialty gift cards, customer loyalty, and community rewards programs to Independent Sales Organizations (independent companies used by banks to develop new merchant relationships on their behalf). ISOs then sold these gift and loyalty products to merchant customers along with credit card services and processing equipment.
In 2009, Sparkbase managed gift card processing for over 12 million alternate payment system cards, with an average daily balance of approximately $120 million. The company developed its own network code in-house, with twenty-three developers on staff, and operated its own servers and Tier V data center on site, with off-site secondary and tertiary backup data centers.
