Projects we maintain

Our Open-Source Programme Office is bigger than usual. We refer to it as our mOSPO, because of its size and the engineering muscle we have added to the team.

Caterina Director of Community

Our Open-Source Programme Office

The size and scale of our programme office allows us to make significant and impactful contributions to essential projects for the community. We’re proud to have OSPO developers merging PR’s directly on Kubernetes, chairing the technical committee for OpenStack while others are adding significant features as maintainers on Apache Ozone. This is only possible because of the scale of our team and the resources we dedicate towards open source.

Our OSPO helps drive profit, proving that private organisations can support the open-source ecosystem as well as their own bottom line.
