Enterprise pricing starts at $1500/mo and scales up depending on your requirements. It is necessary for communities that require custom authentication methods, special plugins or do extremely high traffic. Is there a reason that you think our Enterprise plan might be necessary here? You can find more info at Discourse Enterprise | Discourse - Civilized Discussion.
