Plus Three was off to a good start when the software and consulting firm took on the Democratic National Committee as its first client, overhauling the organization’s Web and email capabilities, and building the open source, database known as “Demzilla.” Though the firm no longer works with the DNC, it has since served many of the largest democratic and progressive organizations in the country, developing customized software, campaign strategy, and design services. “We’ve come into the market in a very unique way,” affirms Plus Three’s president and co-founder, Juan Proaño.
