Looks like a collective effort started by a group of authors and artists. Seems to rely on fundraisers for capital. Books tend to have poor Amazon sales rank (the best I just found were around 300K and 600K sales rank, the rest were No Data or in the 1,000,000+ range.
They've been around since 2012, and published a limited number of books - that's better than pumping out dozens of poorly produced and unsupported works. I have no idea how they market beyond word-of-mouth on social media.
I don't know enough about it to think 'skeevy', just 'poor business risk at this time.'
