The Definitive Guide to Product Discovery

The service

The business card that’s a book

In every field, the person who wrote the book outranks the person who wrote the deck. Consultants, advisors, coaches, fractional executives: your next client is comparing you to someone — and “they wrote the book on it” ends the comparison. A book is the one credibility asset you can hand a prospect that keeps selling after the meeting ends.

You know the options. Write it yourself: five hundred hours you’d otherwise bill. Hire a freelance ghostwriter: months of back-and-forth, and editing, design, and publishing are still on you. Or an agency: $50,000 and up — where most engagements end at a manuscript rather than a published book, and the full-service firms that do publish measure their timelines in a year, not 60 days.

The Expert Book is ghostwriting, productized: the same Leanpub pipeline behind our founder-led books — GhostAI drafting from your recorded words, professional editing, fidelity checks on every chapter — at the price the process makes possible, all-in through publication everywhere.

The definitive book on what you do is still unwritten. Publish it, and every pitch you make afterward starts from “I wrote the book on this.” Instant credibility, compounding forever.

How it works

You talk. GhostAI writes. A Leanpub editor refines. You approve.

You talk. One deep recorded interview — 90 to 150 minutes, booked at checkout — where GhostAI and your Leanpub editor interview you about the thing you know best. We build your book’s outline with you in the same session. Plus everything you already have: talks, posts, podcast appearances, internal docs. It all feeds the draft.
GhostAI writes. GhostAI is the suite of AI skills we built at Leanpub on Anthropic’s frontier model, Claude Fable 5. It studies your recorded interview and your writing samples, learns your voice, and drafts your book in it — and every chapter is checked against how you actually talk. Fidelity to your voice is measured, not assumed.
A Leanpub editor refines. A professional editor from the Leanpub team — working with the AI editing tools we built — reviews and refines every chapter before you see it. The process is the product: the same pipeline behind our founder-led books, run by the team that built it.
You approve. You get the whole draft, then two recorded review sessions with your editor: one to react to the whole book and go deep where you want, one for final touch-ups and sign-off. Nothing publishes until you’ve approved it.

You choose whether to ship with a colophon — “How this book was made” — disclosing the method: recorded conversations and your writing samples, drafted by GhostAI in your voice, checked chapter by chapter, refined by a Leanpub editor, approved by you.

What we never do is ship words you haven’t approved. Everything passes our fidelity checks, your editor’s review, and your sign-off before it publishes.

What's included

One Price. Everything Included.

No tiers, no add-ons, no founder’s calendar to wait on. The Expert Book is the productized version of the process — which is why it’s the affordable one, and why it never has a waiting list.

Your time

Your effort budget, to the minute

Your expertise is the product; your time is the constraint. Here is the entire budget:

What	Your time
The half-hour call that starts it	30 minutes
The interview — the thing you know best, out loud	90–150 minutes
The draft review session — the whole book lands; you react, we go deep	60–90 minutes
The final review session — touch-ups and sign-off	60–90 minutes
Total	Under 6 hours

Our promise:
“You get a real, published book on your expertise in under 6 hours of your time — with zero writing.”

A book normally costs its author over 300 hours of writing. Yours costs you under six.

Frequently asked questions

FAQs

Is it my voice?

Yes — and it’s checked, not assumed. GhostAI drafts only from your raw material — your recorded interview plus your writing samples — and every chapter is scored against how you actually talk. Your editor refines before you ever see it, and in your review sessions you flag anything that doesn’t sound like you.

Do I approve everything?

Yes — you get the whole draft, then two recorded review sessions: one to react to the whole book and go deep where you want, one for final touch-ups. Nothing publishes until you’ve signed off.

Who owns it?

You do. Copyright and royalties. The book publishes under your name — on the Leanpub store and on Amazon.

Who actually works on my book?

A professional Leanpub editor runs your engagement end to end, working with GhostAI — the same pipeline behind our founder-led books. The process is the product: it doesn’t depend on any one person’s calendar, which is why it costs less and never waits on a slot.

Isn’t this AI slop?

No — this is ghostwriting, productized. Business books have been ghostwritten for as long as there have been business books: Lee Iacocca’s autobiography — the defining CEO bestseller — was written with William Novak, and David Goggins wrote Can’t Hurt Me with Adam Skolnick. We do it proudly — and honestly: the great literary memoirs take hundreds of interview hours and years of writing, and we’re not claiming that. We’re claiming a sharp, polished, professional book in your voice, in 60 days. Slop is undisclosed, unaccountable generation. This is the opposite: drafted only from your recorded words and writing samples, checked chapter by chapter against your voice, refined by a professional editor, and approved by you before anything publishes.

What do the more expensive versions add?

Both add a Leanpub founder. The Founder Book is the same machinery, compressed for a startup founder on a deadline: led personally by a Leanpub founder and published in 28 days — scheduled around your Demo Day — with the print run, podcast episode, and launch video to match the moment. The Executive Book is the deep partnership: a dedicated Leanpub founder works with you across three to five deep interviews and up to three review sessions, on a bigger book — 25,000 to 50,000 words — published in 90 days. Same process at every level; what you’re adding is founder attention, depth, and launch production.

Can my company pay for it?

Of course — company-sponsored books are welcome. We support card, invoice, PO, and wire, and we’ll work with your procurement process.

It starts with a half-hour call

Thirty minutes with the Leanpub team. We talk through your expertise, the raw material you already have — talks, posts, client work — and what your table of contents could look like. If we don’t believe there’s a book in it, we will say so right on the call.
