About Us

VerticalChange exists at the intersection of data-driven decision making and cutting edge technology.

Company History

Subvertical LLC, a California company, was formed in 2012 to address an unmet need for modern technology to address the data management and analysis problems facing the social service and public health sectors. Recognizing a need for more flexible, affordable, and easy-to-use tools for data collection and reporting, Subvertical worked closely with a representative group of service providers to release VerticalChange in early 2013.
