Cloudup has morphed into a new identity as sort of a dropbox meets apple photostream mashup... except it's better than both of those products as a visual asset database.
You can upload up to 1000 items into your account, you are allotted 250GB of space for free.
Once your stuff is up in the cloud in your account (via their desktop app or your browser)... you can share your "streams" with people. Like Slack, when you are connected to people, you can share everything in real time.
That's all awesome... but I don't care about any of that. Cloudup is the only lightweight easy to use cloud software I've used that can handle libraries of vector files visually.
Web based DAM (Digital Asset Management) Software is expensive and is usually overladen with features and service contracts.
Cloudup is doing a better, cleaner job of taking care of my vector files in a drag and drop cloud based interface... for free. They don't give me any money, I am not an affiliate, I completely stumbled on their product and I am probably using it in a non-spec way... but they did a good job.
