Project Jupyter is an open-source software project and community that builds software, services, and open standards for interactive computing across dozens of programming languages. The core of Jupyter is the Jupyter Notebook, an open document format and web application that enables users to compose and share interactive programs that combine live code with narrative text, equations, interactive visualizations, images, and more.
Because Project Jupyter did not participate in the interviews, including our pre-interview questionnaire, these elements are missing for Project Jupyter in the information above. While the Project Jupyter team kindly provided feedback on the rest of the presented information, they were unable to provide detailed financial information prior to release. The amounts presented for revenue and expenses are determined from the NumFOCUS annual reports. These are incomplete and likely inaccurate. Additionally, the Project Jupyter team noted they receive funding from a number of sources that don't disclose their grant funding amounts publicly. As per our guidelines, these funding sources aren't included in this analysis.
