Starter and Individual are single-member workspaces — one active membership, of any role. Team and Enterprise add unlimited members at no extra per-person cost.
Why the meter is usage, not headcount
Amolfi does not charge per seat. Each organization shares one usage pool, and what you spend scales with how much work Amolfi does — not with how many people you add.
That’s why Team can support unlimited members: adding a person costs nothing extra per head, because what’s metered is the work, not the seat.
