This is going to affect companies like yesware.

I don't know where you get the idea that there are not good choices for on-premise, file share and sync solutions. There are products like filecloud (http://www.getfilecloud.com) which have been solving this pain very nicely.

On iOS, even AeroFS kind of sucks, due to some horrible decisions Apple made. Basically every app has to adopt every storage provider's API, and right now, only Dropbox and maybe Box have any takeup. (and iCloud, of course, but iCloud sucks a lot, isn't self-hostable or even enterprise hostable, and is horrible.)

That sounds like a problem with iOS, not AeroFS.

I've been struggling to find a good Dropbox alternative for on premise. Aerofs is missing the option to share a folder/file through a link to non-aerofs-users which is vital to our workflow.

This filecloud is interesting, thanks. Any other product that you are aware of? I thought I had found them all, but you never know :)

Filosync (my product) has share via link to non-users (users who don't have the client app installed). http://www.filosync.com (I'm the guy who wrote Arq, the Mac backup app, too).

Thanks, very interesting and looks promising. We're a mixed Linux and Mac shop, so we would need a Linux client as well.

OK. Those are on our to-do list.

Giovanni, give me a shout at yuri@aerofs.com -- sharing folders/files through a link is on our roadmap
