Rough numbers here because BOX hasn't reported full 2017 yet but: Dropbox 2017: $1107M Revenue Dropbox 2017 Paying Users: 11M ARPU: $100 [1] Box.com (Q4-16 to Q3-17): $479M Revenue Box.com (Q3-17) Paying Users: 9.7M - 10.2M [2] ARPU: $47 - $49 [3] [1] $1107/11 [2] "over 17% of our registered users [57M] were paying users" [3] 479/10.2 to 479/9.7
Wow, I assumed that Box would've had a higher ARPU given it's focus on enterprise.
Though simply looking at per user per month pricing:
Dropbox for Business has $15, $25, and Enterprise
Dropbox Individual has Free, $10, and $20
Box.com has $5, $15, $25, and Enterprise
The math doesn't even really make sense though. Dropbox's ARPU is $8/user/mo whereas Box is $4/user/mo. Either the my math is wrong or Box offers some pretty steep Enterprise discounts that work out to <$5/user/mo.
