Over the past decade science's need for software has grown but the funding and career positions for software developers has not kept up. In 2011, a group of scientific software developers formed NumFOCUS to answer this need. NumFOCUS is a 501(c)(3) nonprofit that supports and promotes world-class, innovative, open source scientific computing. We are one of many nonprofits that have come into life over the last five years to help software projects sustain. We do through partnering with corporations that use our tools and helping software projects maintain a level of governance that is required for such partnerships. Here we will discuss, who, what, and how we support our projects.
