How Mustachian Post Built a High-Trust Business Through Print-on-Demand
A CASE STUDY
Lulu Overview
Lulu is the global leader in creator-focused print-on-demand publishing. With flexible printing options, automated fulfillment, and seamless integrations—like Lulu Direct—creators maintain full ownership of their content while building scalable, sustainable revenue streams.
Lulu eliminates inventory management, upfront printing costs, and complicated vendor contracts, making it easier for creators to monetize their expertise on their own terms.
The Problem
Marc's platform grew quickly, but his content library expanded even faster. After years of publishing long-form, detailed articles on Swiss investing, budgeting, and FIRE principles, new readers struggled to navigate his massive catalog. Swiss personal finance content is often fragmented, overly technical, or adapted from US markets—leaving everyday readers overwhelmed and under-informed.
Marc needed a way to:
The Book
Free by 40 in Switzerland is a comprehensive guide that organizes years of Marc's research, content, and experience into one actionable framework. Available in three languages, the book introduces exclusive topics, deeper explanations, and chapter-by-chapter exercises for readers to implement immediately.
It serves as a permanent reference, complementing his digital content with a structured roadmap readers can revisit throughout their multi-year journey to financial independence. A factor in his financial freedom, the book generates passive income and in an integral product in the overall business strategy.
Without leaning on social media to attract new readers, the book is promoted to his audience using email marketing and search engine optimization.
From Blogger to Bestselling Author:
The Solution

The result: a book that solved both the audience's need for clarity and Marc's need for a scalable, long-term revenue and brand asset.

Marc explains. "Before switching to the Lulu API, I was spending 1–3 minutes per order manually entering customer details, addresses, credit card info—one form at a time. I even had my virtual assistant help, but it was still time-consuming and error-prone and costly. Since moving to Lulu API, it's night and day: orders are automated, reliable, and take literally zero minutes of my time (and of my virtual assistant invoices!) It's been a total game changer."
The result: a book that solved both the audience's need for clarity and Marc's need for a scalable, long-term revenue and brand asset.
Data, Results, and Launch Strategy
Book sales growth came primarily from search engine optimization and word of mouth. Marc built hype around the book using his newsletter and by delivering 40 beta readers the chapters as they evolved. The book achieved bestseller status in Switzerland (a country of ~9 million people) with a sustained evergreen sales cycle, and more than 3,500 units sold to date.
Most purchases followed a consistent path; from SEO or referrals to the blog, then the newsletter, and ultimately the book. By selling the book directly on his own website, Marc kept readers within the Mustachian Post ecosystem, creating a seamless purchasing experience, immediate revenue, and reducing friction with an offsite bookstore. He also credits a simple tactic—the book's prominent placement in the site's top navigation—as a key contributor to its success.
Perceived value played an important role as well. He has only discounted the book with a special offer twice, celebrating business milestones of the blog's ten-year anniversary and the book's bestseller status, which in turn sparked sales. Positioning the book's value parallel to his business is the long-term strategy Marc seeks, offering credibility and building trust with readers.

The result? Marc explains, "The book helps with credibility and authority around the topic of financial independence in Switzerland. Some people call me their 'lighthouse' about this topic. Not solely about the book, as the blog carries most of the weight, but the book reinforces this strongly. Positive media and reviews in turn bring new readers."
