What is a NumFOCUS "Sponsored Project?"
NumFOCUS provides a stable, independent, and professional home for projects in the open source scientific data stack through our fiscal sponsorship program. In exchange for a small percentage of funds directed to the project, sponsored projects acquire nonprofit charity status and receive a variety of financial, legal, and operational services provided by NumFOCUS.
NumFOCUS Affiliated Projects
In addition to our Fiscal Sponsorship Program, NumFOCUS maintains a supportive relationship with our Affiliated Projects. Affiliated Projects are focused on open source data science and make meaningful use of NumFOCUS-sponsored tools. Unlike Sponsored Projects, Affiliated Projects are not fiscally sponsored by NumFOCUS. We highlight affiliated projects to encourage the community to contribute to, promote, and support these open source tools!
I use the tools supported by NumFOCUS almost exclusively, and it is difficult to imagine that something this meaningful can be both free and open!
