Present a unit-economics model like an FP&A partner: the assumptions, the sensitivity, and why it scales.
Every AI design tool carries the same tension: usage grows, and the AI inference bill grows with it. Open Design breaks that link with BYOK — bring your own key.
Under BYOK, model inference is billed straight from the user's own provider account, never resold through our infrastructure. Our own cost per seat is $0.42 a month — storage, sync, relay, nothing more.
The result: gross margin holds at 97.8% whether a seat runs ten generations a month or ten thousand. This deck walks the assumptions, the sensitivity, and the forecast.
The chart only matters if the assumptions hold. Here is every input to the model, published in full — nothing modeled here that we would not show a CFO directly.
Usage can grow tenfold and margin does not move — because the AI bill isn't ours.
Hold pricing flat at $19 per seat, lean on BYOK as the retention lever, and let team expansion — not AI resale — drive revenue. The model holds at 97.8% margin through 15,000 seats.
