 [Splitgraph](https://www.splitgraph.com) is powered by data. We use [Metabase](https://www.metabase.com/) to build BI dashboards that can answer questions about how people interact with us. These dashboards reference our Web analytics data, user data and all events happening across the estate. We can find out how many people queried the Splitgraph [Data Delivery Network](https://www.splitgraph.com/connect) on a given week, how they found Splitgraph, or if they ever pulled a data image.
