We're particularly fond of Dropbox as a collaborative work tool, but it's not a system that works for everyone. Receivd, on the other hand, is a ridiculously simple way to share files in real time that's really easy for anyone to do. Currently it's in private beta, but we've got 2000 invites so you can check it out for yourself.
Note: Received works on all platforms via the web, but it currently only has a desktop app for Mac OS X. That said, the web app is pretty robust and comparable to the desktop experience, so don't be discouraged by the lack of a desktop app for other platforms. They'll be coming (along with mobile apps) in the future, anyway.
Receivd is a simple concept: you add contacts and securely share files with them. What's special is that it all happens in real time. When you share a file with a friend, and that friend is running Receivd in his/her browser or on his/her computer, it shows up right away. On the desktop app, contacts receive notifications of new files as well.
Sharing a file is pretty simple. You just drag it in to the drop space and choose recipients:
It works just the same in the web version:
When you receive files, they'll show up in your inbox:
If you want to share with more than one person, you can create a list and add a bunch of people to that list:
That's pretty much all you need to know to get started. If you want to try Received, you just need to enter the code LIFEHACKER on the Receivd signup page.
Please enter this code on the site and do not email it to us as emailing it will do nothing.
