Two things cost money when running the AI CMO: the ad spend itself and (depending on plan/setup) a platform fee.
Running on your own Meta ad account:
- Ad spend is billed by Meta directly to your ad account's payment method, it never goes through Larven.
- Larven's platform fee on that spend: 12% on Starter plans, 0% (free) on Pro. The fee is charged separately by Larven based on your actual Meta spend. Upgrading to Pro stops the fee from the next cycle.
Running on Larven's managed account:
- Larven charges your card the daily ad budget and spends it on your ads.
- A 12% fee applies on both plans (5.5% payment-provider costs + 6.5% implementation and support).
Your subscription credits are separate, they pay for creative generation, not ad spend. See Understanding your charges if a line on your statement is unclear.
