25M registered users but I wonder how many of those are active? Box has been quite active with their promotions of free storage space, but the actual limitations on the service made this free space not very useful.
I loved having 50GB for free, but couldn't stomach using the product. Their absurd process for selecting a custom location for the Box folder, from their own website, included uninstalling the software and doing some registry magic by hand. With that kind of attention to detail, I couldn't have any trust in their engineering or product teams.
The idea that actual enterprises would entrust their data or operations with a company I wouldn't use for casual syncing of unimportant data is something I'm still trying to stomach.
