12,480 rows, 9 columns. Cancellations concentrate in Starter: 418 of 521 came from the 6,240 Starter accounts, a 6.7 percent quarterly rate against 1.9 percent on Growth (91 of 4,800) and 0.8 percent on Scale (12 of 1,440).

The Starter median account age at cancellation is 41 days, which puts most of the loss just past the trial to paid handoff rather than at renewal.

The 41 day median says so, and the cohort split backs it: Starter accounts that used the API at least once in week one churn at 2.1 percent, the ones that never did at 9.4. Price is the same for both.

Nothing in the product. It is the second invoice, and it is the first time the charge arrives without a trial framing around it. The people who never found a use for the thing are being asked to pay for it a second time, and that is the moment they answer.
