That most likely is an option, where DataDog (and others) will happing sign an enterprise contract with you and take more of your money than what you end up using. The issue is that you're still going to be bound to a maximum logging/metrics/etc budget, so you still end up needing to estimate your usage to avoid going over your pre-paid limits.
