"Create groups, send links, share files and we’ll organize them so you don’t have to" <- This doesn't mean much to me. Maybe I didn't 'identify' with the problem you're trying to solve.<p>If I understand correctly, you're a service that uploads e-mail attachments to a central location? Kinda like sending all -mail attachments to google Drive, then sorting by who you send to?
I like your design, and the message was quite clear. It didn't take very long to find out was your product does and was value it can add to a group workflow.<p>The parallax effects on the front page aren't very smooth when scrolling though, and my personal opinion would be to have the Russia/English navigation item displayed as the last item rather than the first. Other than that, it looks great!
I understand what you're doing, but the plans (at least in English) are quite confusing. Technically they are all month to month plans, but naming them "Month" "Year" and "Eternity" is rather confusing. I would definitely think about renaming them to something not having to do with a date range.
Short: no. I'm guessing it's about sharing files and commenting on those shared files. But, that's a guess. So, try another version of your explanation.
I got the general idea of 'better shared files', but it only really made sense when I saw the screenshot. I'd suggest moving that further up.
