I'm somewhat astounded to hear they have 972 employees. I would have guesstimated somewhere below 200. Even with a huge marketing push, I'm a little at a loss for what they all do.
They have a much higher-touch enterprise sales process, so my guess is that most of the extra employees vs. DropBox are sales, customer service, relationship management, etc. Even after the sell, big clients tend to want dedicated account managers, dedicated support staff they know by name, etc. (Still, it does seem like a lot.)
Are you fully aware of what they offer? They have all kinds of well-known and arcane certifications, integrations with a few dozen products that are only relevant to large enterprises, a pretty big third-party ecosystem and the API to support them, and the large team required to sell and support these tools.
It's not just file storage for five bucks a month.
Well, it kind-of explains why they have the losses they have.
In business, usually it's possible to achieve whatever revenue you want; the hard part is getting there without a headcount/other expense basis that makes you bleed money instead of earning it.
Edit: You were before me, so added my comment as a reply to you instead.
