NumFOCUS Membership Program
Powering Open Source Science & Innovation
Scientific open-source software (OSS) powers every sector of modern research and industry. From decoding the human genome to modeling climate change, designing life-saving drugs, and advancing AI, these tools and communities call NumFOCUS home. Our projects fuel breakthroughs in science and technology, equipping universities, research labs, government agencies, and industry leaders with the tools to address today’s most complex challenges.
Supporting NumFOCUS ensures the foundational tools our members depend on remain accessible, secure, and adaptable for the future.
Reliable Funding & Engagement
We are in the process of transitioning corporate sponsorships to our new Institutional Membership Program. NumFOCUS members will have increased opportunities for engagement with the NumFOCUS community, while supporting the critical work of our projects.
The NumFOCUS Membership Program was created with two goals in mind:

About Bloomberg
Bloomberg connects influential decision makers to a dynamic network of information, people and ideas. Our strength – quickly and accurately delivering data, news and analytics through innovative technology – is at the core of everything we do. Key participants in the financial markets depend on Bloomberg’s core product, the Terminal, to trade, manage risk, consume information, and navigate time-critical decisions. This means we must leverage the best technologies available for all of our projects. As a longtime proponent of open source technologies, our developers are also significant contributors to many projects including Apache Solr/Lucene, Apache Hadoop and OpenStack, and we publish many of our own projects on GitHub. We are always looking for new ways to work with, analyze, and display our data and often choose Jupyter to rapidly develop prototypes and share results with others across our data science, machine learning and quantitative research teams. Bringing Jupyter to Bloomberg also means we are actively contributing to the community.
