Zibby Books was founded by Zibby Owens, an established book influencer, as part of her company Aibby Media. You can read more about her launch of Zibby Books, here, and here. Both articles focus a lot on the royalty structure. While writers still receive advances and royalties, they will also be part of a profit sharing program which divides 75% of all net profits equally between the author and the company’s employees. I didn’t see any articles about this policy changing, so I have to assume it is still in place.
The first book they published came out in 2023 and you can read more about it here. They primarily publish fiction and memoir and they are open to agented and unagented submissions. You can see all the books they’ve published so far, here, to get a feel for what they are interested in. They also make it very clear that they are not interested in science fiction/fantasy, poetry, historical fiction, historical biography, romance, self-help/parenting, political, or children’s books.
They ask that unagented authors submit a brief synopsis of the book including comparable titles, an author bio, and the full manuscript.
They have a submission form and you can submit via email. It’s not clear which is preferable, but when in doubt I always go with email submissions. They only respond if interested and do not give a deadline in terms of when to assume rejection.
