Is your data
graphdefined?
GraphDefined helps you to make sense of the increasingly complex world of linked real-time data.
No compromises on security, privacy, and semantics.
For E-Mobility
From the German calibration law, over charging station management and EV roaming towards grid management. Since 2012 we provide best in class open source solutions for charging your electric vehicle securely and privacy-aware and for exchanging all required data sets between all market participants.
For Smart Cities
Cities need to reinvent themselves to become digital. Todays citizens do not want old bureaucracy relabeled as new E-Government services, they want access to open information, Open Data and Open APIs.

And of course: What happens in a smart city, stays in the smart city!
For E-Health
Smartphones and smartwatches change dramatically the way how we collect and analyze valuable health data about ourselves. At the same time new medical devices within the Internet of Medical Things (IoMT) provide emergency medical care wherever you are. We provide the infrastructure for 24/7 real-time operation and an active post-market device surveillance (MDR).
