A seat is equivalent to a team member. Any team member with a dedicated login and password to access Xeno is considered a seat as soon he/she has logged on at least once to Xeno. A Xeno account is dedicated to a company. As a partner, you are only limited by your Partner number of seats and you can allocate your available number of seats as you like over any number of accounts you want.
This area is dedicated to our Partner Program documentation.
