My partner, as well as one of my very good friends, have published several stories with them. The company is very transparent and a pleasure to work with, and from what I've heard, most of their authors are great people. My partner has always received royalties on time, with a very clear break-down of sales and such. Edits are always completed in a timely manner, too.
I think this is their fifth year in business? I remember my partner mentioning that one of the owners said that August 2014 was their best month yet, so the company seems to be going strong. (However, they're not the biggest in business when it comes to queer romance. Off the top of my head, I think Riptide, Dreamspinner and Samhain are bigger and probably do more sales.)
They publish everything now except for traditional straight romance (so, nothing cis-gendered guy/girl), which includes stories with transgender protagonists, poly relationships, etc. They're pretty easy to get into, too - I'll be considering them when I'm ready to submit, but I might go for the bigger publishers first.
