We purchased Chartio as an internal BI tool to provide teams external to the data engineering team access to reporting data. We did this for the purpose of ad-hoc analysis. We are a smaller company, so we used Chartio to build visualizations relevant to other teams that they can access and then use in their day-to-day. For example, we would build dashboards that the customer success team could use in their QBRs. In reality, it was meant for the entire org to use, but it ended up being used by engineering and product and consumed by other teams.
