$300 a month base plus 5 percent on top of token cost, for the whole company. A typical active team lands in the low hundreds total; even heavy use stays a fraction of one per-seat AI rollout, because there are no seats.
The variable part scales with actual work done, answers given, jobs run, agents acting, and you see the token line transparently, so the bill explains itself.
Compare honestly against alternatives: per-seat copilots at $20 to $30 a head cross Heidi's total cost at a dozen users, and Heidi covers everyone, plus the API, plus the agents.
