Most books disappear thirty days after launch.
Yours shouldn't.

A book is not a vanity project, and it is not a one-time publishing event. Done correctly, it is the single highest-leverage authority asset a leader can build — the source code for media, speaking, content, credibility, and inbound demand for the next decade.

Mangus partners with leaders who have something genuinely worth saying, transforms that expertise into a serious manuscript, and then engineers the manuscript into a full authority platform — so the book doesn’t just exist on a shelf, it earns returns every month it stays in print.

Most books disappear thirty days after launch.
Yours shouldn't.

Each stage produces specific deliverables. No black boxes, no vague creative work hidden behind retainers. Every milestone is documented, dated, and signed off.

“I'm a big fan of Jeff's. Without his support, first convincing me to write Inventor Confidential and then supplying his companionship (both personally and professionally) every step of the way until it was published, I never would have gotten started. For me, the book is a reflection of what I believe to be core tenets in the American grassroots innovation space. It's been invaluable to share these tenants with so many an a way that is understandable and can be reread whenever inventors need to get back on track. Thank you Jeff! "

A clear distinction

Generic ghostwriter vs. Mangus.

Most ghostwriting services deliver a manuscript and disappear. Mangus delivers a book engineered as a business asset — and stays through the campaign that makes it pay back.

FAQ

Engagements typically range from the mid-five to low-six figures depending on manuscript scope, research depth, author availability, timeline, and whether the work includes the full Authority Campaign. A custom proposal is built after a discovery call, and pricing is quoted on a fixed-scope basis — never hourly.

Yes — and it's the most important part of the engagement. The process begins with six structured interviews, voice mapping, story extraction, and three full revision cycles designed to preserve the author's exact language, cadence, worldview, and intellectual edge. Drafts are read back to you. If a sentence doesn't sound like you, it gets rewritten.

A serious nonfiction book takes 9 to 14 months from kickoff to publication-ready manuscript. That covers positioning, interviews, outline approval, drafting, three revision rounds, editing, and proof. Faster timelines are possible for shorter formats, but rushed manuscripts read like rushed manuscripts.

That's the entire point of the Authority Campaign. A finished manuscript is engineered into 52 LinkedIn posts, 24 newsletter essays, 12 podcast talking-point packets, targeted pitch angles for tier-1 publications, and a keynote framework. Authors typically reach 35K+ in the first 12 months post-launch, with measurable inbound from podcasts, speaking inquiries, and consulting conversations.
 
 
 

Yes. In every Mangus engagement, the author retains 100% of the copyright, royalties, and intellectual property in the final manuscript. Specific terms — credit, confidentiality, and any optional collaboration billing — are defined in a clear written agreement before any work begins.

No. Every Mangus manuscript is human-crafted, end to end. AI tools are not used to write, draft, or generate chapters. The reason is simple: AI cannot capture a real voice, cannot conduct a real interview, and cannot make the editorial judgments a serious book requires.

Mangus works with executives, founders, consultants, public figures, category experts, and serious thought leaders. The common thread is that the author has hard-won expertise, a real point of view, and a commercial reason for the book to exist beyond vanity.

That’s common. Many authors come in with a half-finished draft, scattered chapters, or a manuscript that doesn't sound like them. Mangus offers a Manuscript Rescue engagement that audits the existing work, restructures the narrative, rewrites for voice, and finishes the book to publishing standard.
