About the manufacturer
ZipGrade LLC is a unique startup company founded by John Viebach. John's wife was teaching an SAT prep class in the evening in a borrowed classroom. Without access to an OMR machine, she was manually evaluating the bubble answer sheets at the end of each class. John started working to create an economic rating app for the iPhone.
