About Us


We are Proteon Software. Our mission is to create world class membership portals for non-profits, associations, and other federated organizations. We all admire the glamorous work of charities, non profits and their donors, but to do this work they need business-class tools and processes that enable them to get things done. We believe that people have all the knowledge they need to create the solution perfect for them, and they need only be provided the tools and the processes necessary to make them a reality. Our vision is a world where non-profits aren't held up by dated tools or old membership management methods. We envision a world where technology is seamless, and gets out of people's way and allows them to pursue their work on their terms.
