 Jaeger is hosted by the [Cloud Native Computing Foundation](https://cncf.io) (CNCF) as the 7th top-level project (graduated in October 2019). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Jaeger plays a role, read the CNCF [Jaeger incubation announcement](https://www.cncf.io/blog/2017/09/13/cncf-hosts-jaeger/) and [Jaeger graduation announcement](https://www.cncf.io/announcement/2019/10/31/cloud-native-computing-foundation-announces-jaeger-graduation/).
