Traffikoo Publishing is the book-publishing arm of Traffikoo LLC, blending two decades of performance marketing and technical expertise with modern publishing craft. It brings together an in-house imprint, a dedicated book marketplace, and an AI authoring toolset under one roof — Ephyia Publishing, MixCache.com, and Qyx AI Book Creator.
Our imprint, Ephyia Publishing, primarily publishes in-house titles across a range of nonfiction genres — history, travel, professional development, narrative nonfiction, and practical guides — with select outside authors and works of fiction considered on a case-by-case basis. The catalog has grown to more than 2,000 titles, each released in ebook, paperback, and hardcover formats.
A great book deserves more than a great manuscript. It deserves a publisher that understands how readers discover, evaluate, and choose what to read in a crowded digital marketplace. That's the edge we bring — and it's why we built our own marketplace and authoring tools rather than relying solely on third parties.
Our team combines deep performance marketing experience with technical expertise and modern publishing tools to take a book from concept to distribution. The result is books that don't just sit on a shelf. They reach the right readers, build lasting credibility, and hold up long after the launch window closes.
Traffikoo Publishing spans the full lifecycle of a book — from writing and editorial to retail and discovery.
Our in-house publishing imprint, founded in Dallas, Texas in 2024. Ephyia develops and releases 2,000+ nonfiction titles spanning history, travel, professional development, and narrative nonfiction, with select fiction and outside-author submissions considered case-by-case.
Our own book marketplace and self-publishing platform, home to 21,000+ ebooks and audiobooks across fiction and nonfiction, plus an unlimited-access subscription (MixCache Total Access) and tools for outside authors to sell direct to readers.
An AI authoring suite that helps writers move from concept to a complete, publication-ready manuscript — with web-researched nonfiction content, editable chapter outlines, and AI-generated cover art — in a fraction of the time and cost of traditional ghostwriting.
