Intermundia Publishing is building a modern trade publishing company designed to better align the interests of authors, readers, and the publisher. We acquire and professionally publish fiction while treating authors as creative partners—giving them meaningful involvement in editing, cover design, formatting, and positioning, along with higher royalty potential and performance-based incentives. We’re also building readership into the model through giveaways, author access, events, and other rewards that encourage readers to discover and champion new books. For emerging authors, we provide hands-on guidance through the publishing process rather than simply acquiring a manuscript and taking control of it. The problem we’re solving is the misalignment in traditional publishing: authors often surrender significant control and economics, readers are largely treated as end customers rather than participants, and new writers have little visibility into how publishing actually works. Intermundia aims to create a scalable trade publisher where authors are partners, readers are incentivized to engage, and everyone benefits when a book succeeds.
