How the pricing model works
The commercial unit is the participant report: the document and action-tracking workspace created for each leader in the campaign. Raters are invited because they have a view of that leader’s work. They are not billed as extra seats.
That matters when an executive needs peers, reports and a stakeholder, or when a manager cohort needs enough raters for the feedback to be useful. The organisation is not penalised for inviting the right people.
