The founder rate is a permanent commitment to the first 100 LMTs who subscribe through this site. As long as your subscription stays active, your monthly rate stays $29.
If we change the product significantly, the rate stays. If we raise the price for new customers, the rate stays. If you cancel and come back later, you come back at the prevailing rate at that time. The promise is permanent for the original 100, contingent on the subscription being continuous.
The 100-slot counter is real. It counts subscriptions converted from trial to paid at the early-adopter price. Beta cohort grants don't consume slots. When the hundredth slot fills, the price returns to $49 for new subscriptions, and we'll publish a quiet note here saying the slots are gone.
