The real power of this product is as a replacement of BI/Visualization tools. Imagine being able to connect Rows to a database and create "governed" sheets that look/work like dashboards with charts, tables, filters, etc.

It would be a killer product because most users are familiar with spreadsheets already. Many users end-up copying data from dashboards into spreadsheets (gsheet, excel, etc) so why not skipping the intermediaries and go straight to delivering a hybrid of dashboards and spreadsheets.

Lots of potential.
