Open Science Champions

NumFOCUS calls our individual supporters Open Science Champions. There are several ways to champion our mission of making scientific computing more open and accessible. NumFOCUS depends on advocates and volunteers like our Board of Directors and PyData committee members to help us better serve our Sponsored and Affiliated Projects. Our Projects rely on contributors and maintainers in order to develop the open source tools we all use.

Financial support is also vital to the sustainability and growth of our organization. In addition to corporate sponsors, event proceeds, and foundation grants, individual donors provide much-needed resources to our mission of making scientific computing more open and accessible. Donating to a charitable cause is a generous personal choice, and each person has a different capacity to give. NumFOCUS celebrates every donation we receive.

Our goal is to be as transparent as possible about how we use resources donated to NumFOCUS. Below are tiers of annual donation amounts that our supporters contribute to us along with examples of the types of impact that these levels of support help to enable.

Open Foundations

Up to $250 annually | Up to $21 monthly

Our Open Foundations level of support includes the majority of donors to NumFOCUS. These donors form the bedrock of our work toward our open source mission. We believe in keeping the opportunity to support NumFOCUS accessible to all.

At this level, hundreds of smaller donations combine to create baseline impact. Most notably, Open Foundations donors help NumFOCUS provide direct funding to our Projects through our Small Development Grants.
