ARPU for CRWD is higher because they target larger customers than S does. They are both moving in each other’s direction though. IMO, its a strategy difference and probably not as big a deal when identifying differences between the two.
$S has a lot of customers via their MSP partnerships. These partnerships generally target smaller companies. For example, I have $S on my laptop because my company (300 employees) is an MSP thru one of the $S partnerships. We provide these services to a lot of other customers; and the vast majority of these are smaller companies. Think of this kinda like the bill.com model when they partner with banks and such and are white-labelled.
