This is geared towards Inky's Enterprise offering.  Businesses can purchase multiple licenses if more than one employee is going to use Inky.  Each employee needs their own license.  Inky can save businesses significantly by downgrading their existing Office 365 plan and adding Inky in place of the installed Outlook app.  The business subscriber assigns each employee a roster "seat" which allows them to access Inky.   Seat holders on the roster can then tailor their own Inky accounts as they'd like.   If you purchase Inky for yourself, you'll be a roster of "1".
