A: Columns has evolved a lot since the deal was AppSumo.

This deal's product coverage is still completely available which is now called Columns Graph, our main product is now Columns Flow which you can build complete automation for any data process, analysis and visualization.

So it uses usage-based pricing, to support the existing deal buyers and remaining codes on AppSumo, in addition to the access to Columns Graph, you also now get Premium tier of Columns which is priced at $20/m regularly, so it is pure gift. And we will not sell on AppSumo after the remaining codes sold out.

Hope it helps.
