Stan Governing Body (SGB)
The scope of the SGB’s authority is all things Stan. That includes ownership/management of trademarks, online resources like Discourse and GitHub and membership in the Stan community. The SGB has authority over:
- ownership and management of trademarks
- online resources including the Stan Discourse, the stan-dev GitHub organization
- NumFOCUS funds
- fundraising in support of Stan
- authorizing and/or running Stan conferences
- licensing requirements for contributed code and documentation
The SGB is intended to be a transparent body in service of the Stan community and electorate. To this end the SGB will post regular updates about its activities on the Stan forums in the Stan Governance category.
The SGB is to advance diversity in under-represented communities in the Stan ecosystem. The SGB will actively develop and implement strategies to improve inclusion and diversity at all levels of the Stan project and will prepare an annual diversity report.
To reach the current SGB with any questions, concerns, or feedback, please email email@example.com.
The current SGB members are:
- Arman Oganisian (University of Pennsylvania)
- Duco Veen (University Medical Center Utrecht)
- Leah Comment (Foundation Medicine Inc.)
- Max Mantei (University of Hamburg)
- Yi Zhang (Metrum Research Group)
- SGB 2021 general updates
- Minutes of the provisional SGB (08/2018-11/2019)
Stan would not exist or continue to exist without the generous support of grants, foundations, and sponsors.

Stan is now linked to NumFOCUS, a U.S. 501(c)(3) nonprofit organization that serves several other open-source software projects, including NumPy, Julia, Jupyter, and others.
All financial decisions related to NumFOCUS are made by the Stan Governing Body.
The mission of NumFOCUS is to promote sustainable high-level programming languages, open code development, and reproducible scientific research. We accomplish this mission through our educational programs and events as well as through fiscal sponsorship of open source data science projects. We aim to increase collaboration and communication within the scientific computing community.
