I don't see any publishing experience for the owner of the company. I do see a bit of discussion from him about the super, super, super duper high quality of their physical books, but I do not see that those books are in stores or anything else, or that all of their books are available as physical books at all.
I also see typos and grammatical errors in their blurb/cover copy. I do not see any excerpts, and frankly without excerpts the odds of a book selling to anyone but your friends and family are astronomically small.
In short it appears to be a typical start-up, run by people who really like books but don't really know how to produce them and/or sell them. Maybe they'll be a success, but unfortunately I doubt it.
