In my experience, Datadog requires non-trivial active account management internally to ensure a cost effective usage, rather like a cloud infrastructure provider. If you've got 20+ people, it's a no-brainer, the value is immense. Fewer than that and it's a tricky call. It's a great product though, and it's in my list of "things I'd sign up for immediately" if starting a new company.
