In addition to the 408 larger accounts, Cloudflare probably has a large-ish number of accounts with about $50k in annualized billings, as that's a common entry level for their enterprise plans. Those I'd expect to slowly but steadily creep up in billings since Cloudflare introduces new products all the time, they tend to be very easy and desirable for existing customers to adopt, and they tend to be upsells over the base enterprise plan.
