With OpenSlice we take another step in the Network Transformation journey we started some time ago, complementing our open-source toolset with powerful, cloud-native service orchestration capabilities, and allowing us to bridge gaps in the application of standards to network automation.

Our mission

SDG OpenSlice is on a mission to democratize network automation. We are building a Operations Support System (OSS) that bridges the gap between complex infrastructure and agile service delivery, backed by a profound engineering background.

Rooted in the success of the EU-funded 5G-VINNI Project, our platform is built on TM Forum’s ODA principles and infused with state-of-the-art intelligence. We empower operators with plug-and-play network and cloud controllers designed for the real world.

We ensure industry alignment by actively collaborating with leading Standards Development Organizations (SDOs) and open-source communities, including TM Forum, Linux Foundation, ETSI ZSM, NFV, OpenSourceMANO, TeraFlowSDN, and OpenCAPIF.
