Correct. The top tier accounts are $995/month and one of the nifty features are the custom domain short names which, I suppose, provide some nice branding (e.g. amazon.com becomes amzn.to/2U08Yn). The analytics tools are probably also of some value.

Could anyone from bit.ly comment on if this is really enough to keep them in the black? I'm not entirely convinced there would be enough demand. I'm not entirely qualified to comment though either so...
