We founded Plus Three in 2002 with a mission to use web-based technology to promote social change in America. Almost a decade later, we take great pride in our impressive track record of success. We built the best online marketing platform available in its class, and have been able to bring to smaller organizations the same powerful tools we use to run successful multimillion-dollar national nonprofit and political campaigns. Today, we work closely with a select group of some of the best nonprofit and political organizations in the world. We’ve helped raise $250 million and engage over 12 million supporters – educating them and moving them to act in support of the causes and candidates they care about. Most importantly, we bring passion to every project we take on and provide dedicated, personal customer service to each and every organization we work with – and we look forward to working with you very soon!
