Their support staff is very helpful and they seem to put a lot of work into their product. Feature requests are taken seriously and the product is gradually improving.
What do you dislike?
It can run slowly at times, and throw errors, but the support team is helpful in diagnosing issues. Apparently they say they are upgrading the platform to HTML5 soon to make the system more quick & stable. Importing and exporting files requires the additional usage of the Aspera plugin, which isn't that bad in itself, but it requires many clicks, notifications and download managers, even to download a single contact sheet PDF. A drag & drop interface, or one that is a bit more intuitive, would make it much more user friendly.
The massive amount of customization is helpful but can get in its own way sometimes. For example, someone without permission to approve an image can ostensibly send it in a lightbox for someone else to approve, but lightboxes inherit permissions (though it's not explicitly stated anywhere); there is no way for the user to know that the recipient can't actually approve that image through the lightbox, even if the recipient has the proper permissions. Many "features" like this simply take time to get used to and a solid workflow is absolutely necessary to begin with before diving in.
What business problems are you solving with the product? What benefits have you realized?
Our in-house photographers produce many small, complex shoots (1-3 shots every few hours), and this program isn't really built for that sort of workflow, though it is possible. Where it's really helped us is on location shoots, editorial shoots with freelance photographers, etc. When on location or shooting over several days, it's very useful to be able to have photographers upload as they shoot, so photo editors/retouchers can get to work immediately, since time is of the essence and without globaledit this generally takes several additional days. It cuts down the time needed to review images, make selects, and relay notes and markup by a ton. In addition, simply having the ability to store tens of thousands of our editorial assets in the cloud and available via a web or iOS app, giving our entire organization (plus others, if we wish) the ability to see, use or be inspired by them - for a relatively low price - is huge.
