Transloadit wants to raise the bar on file uploads:

File uploading is one of those things that’s completely integral to a lot of web experiences, but very difficult to do well, and not fun at all for developers to spend time on. It’s hard to debug, hard to test, and hard to give progress feedback to users. Transloadit has put the time into making a fantastic uploading service so developers can stop worrying about the mundane details of files and focus on the interesting details of user’s content.

Transloadit is another example of what I like to call service-as-a-service. Just like Zencoder, they’ve focused in on a narrow technical problem that is a pain to deal with, and just developed the hell out of it. Future ventures would do well to leverage these sorts of services: it’s important to focus on the core of what makes an app interesting.

Follow them at @transloadit and check out their blog, which details their attempts to commercialize the service.
