Start with one app, or connect several into something that fits how your company actually runs.
The ones with the most behind them, and a good place to see what an app on Cordango looks like.

The HR person at a fifty-person company gets one record per employee instead of a spreadsheet and a drive folder, and every pay or job change stays as history.

Your team plans in Asana and keeps each project’s cost in a spreadsheet next to it. Put the effort and cost on the tasks instead, and the project adds them up.

For the founder who still does most of the selling: a pipeline board where every open deal has a next step and a date, and a forecast weighted by stage.

Everyone asks the IT or office person for things in chat and in the corridor. With this, every request lands in one queue with an owner and a due date.
Every app here installs on its own and works on its own. Adding a companion is what makes both do more.
