Community Technology Alliance was founded in 1991 to design and construct the technical infrastructure necessary to support the work to end homelessness in Santa Clara County.

CTA has since evolved into a nonprofit focusing on ways for databases and other tools to communicate and exchange data, and on ways to integrate and centrally store data for reporting and data visualization purposes.
