The Open Source Initiative (OSI) is a global non-profit organization dedicated to promoting the benefits of open source software and building bridges among different constituencies in the open source community. Founded in 1998, OSI stewards the Open Source Definition (OSD), the foundational document for open source software, and maintains a list of approved open source licenses. OSI works to raise awareness and adoption of open source software through education, advocacy, and community building.
Serves as the official registered address for legal and administrative correspondence for the globally distributed organization.
As a primarily remote organization, the physical address functions as a mail point rather than a traditional operational headquarters with specific architectural features.
The organizational culture is remote-first, emphasizing collaboration, transparency, and mission-driven work supported by digital communication tools and a global volunteer base.
The registered address provides a legal anchor and official point of contact for the Open Source Initiative, facilitating its operations as a recognized non-profit entity.
The Open Source Initiative supports and engages with the open source community globally. Its functions, including license review and approval, educational programs, advocacy, and community building, are managed by a distributed team of staff and a diverse international Board of Directors. OSI participates in and hosts events worldwide and provides resources accessible to a global audience.
