Our Mission


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