I always find breakdowns like this interesting. Just to get a feel for what others are using, their reasoning, and to generalize what others are spending monthly/annually. With more breakdowns like this from more companies, I think it provides a great understanding of costs. It also can give people a good baseline for understanding what costs are at certain levels of users and with certain functionality.

While I understand that these numbers also give an opportunity for people to point out areas where there may be potential cost savings or opportunities to improve infrastructure, I am not sure generic comments of saying you are spending too much or too little, or I don't spend that much are beneficial. A few key pieces of information that would help correlate these numbers in my opinion are total users on each plan, monthly active users, and the average amount of data required for the users.

Just based off the Stripe numbers I would estimate that they have between 6000-7000 annual paying users (this number may actually be a little lower if the majority of users are paying monthly instead of annually). That does not include members that only trial the service, although I would suspect this number is small.

Long story short, every business has different requirements and usage. What works for one company with 6000 users may not work great for the another company with 6000 users. I just hate seeing people say that someone is spending too much without knowing all the details.
