A seat, not a project.
You pay monthly for each named editing seat. A firm with 20 paid seats counts as 20 on the curve, not as one account.
Pricing
Early belief.
A lasting rate.
The price of a new seat follows a public curve as Graphite4D grows. The rate you join at stays with your seat for as long as it stays subscribed.
Starting rate

Locked for as long as the seat stays subscribed. Before tax.

01 / The principle
The curve moves.
Your rate stays.
A low starting price rewards the people who help an emerging tool grow. A published rule makes the price of joining later easy to understand.
A rate you keep.
Renewals keep the rate recorded when those seats were bought. Adding people later never reprices the seats you already have.
A rule you can inspect.
The curve reads the highest number of paid seats ever active at once. Free accounts and trials don’t move it, and cancellations don’t move it backward.
How a growing team keeps its rates
One team.
Each purchase keeps its price.
An example: five seats bought today, three more added once Graphite4D reaches 800 paid seats. Before tax. Reassigning a paid seat within your firm keeps that seat’s rate.
| Purchase | Seats × rate | Monthly |
|---|---|---|
| First purchase | 5 × $5 | $25 |
| Later expansion | 3 × $30 | $90 |
| 8 seats | Two locked rates | $115 |

No mystery
behind the number.
An S-curve starts at exactly $5, rises fastest around 1,000 paid seats and levels off toward $100. Prices round down to whole dollars.
Formula · normalized-logistic-v2 · USD per new seat per month
σ(n) = 1 / (1 + exp(−0.005 × (n − 1000)))
P(n) = floor(5 + 95 × (σ(n) − σ(0)) / (1 − σ(0)))n is the highest number of paid seats ever active at once, including paid seats not yet assigned to anyone. It is not the number of people using the app today, nor the total number of seats ever sold.
The curve approaches $100 without reaching it, so the highest rate a new seat can be quoted is $99.
Your rate is locked. We reserve the right to adjust this equation in the future. Any change is published here first and applies only to new seats. The rate on every seat you already hold does not change.
Download the parameters & rules03 / The details matter
Clear rules.
Fewer surprises.
How rates are kept, added and ended.
Does the curve change what I already pay?
No. It sets the price of new seats. A seat that stays subscribed keeps the rate it was bought at, every renewal.
What if you change the formula?
We may adjust the equation as Graphite4D grows. A change is published on this page first and only affects seats bought afterward. Your existing seats keep their locked rates.
What happens when my team adds seats?
New seats get the rate quoted for that purchase. Your existing seats keep their original rates, so an invoice can list several groups of seats at different rates.
What if I cancel and come back?
When a paid seat ends, its rate lock ends too. Returning, or replacing a canceled seat, uses the price at that time.
Do unused seats cost anything?
Yes. A purchased seat stays billable while it is unused or unassigned, and inactivity does not pause payment. Cancel seats you no longer need.
Can I move a seat to another employee?
Yes. You can reassign a seat within your firm and it keeps its rate. Each editing seat belongs to one named person at a time.
What happens if subscriptions fall?
The number of paid seats today falls, but the highest count reached stays put. New-seat prices don’t drop with ordinary cancellations.
What about free access, AI and storage?
Free-tier limits and included AI and storage allowances are published in the app before they apply. We don’t promise unlimited AI or storage. Any optional paid usage shows its price and asks for your consent before a charge.
