Audiobook Income Academy Review (2026): What the Mikkelsen Twins Sell Today

Our Take in Brief

Audiobook Income Academy was the course that made Christian and Rasmus Mikkelsen, the "Mikkelsen Twins," famous. It taught a simple pitch: choose a nonfiction topic, hire a ghostwriter, publish the book on Amazon, turn it into an audiobook, and collect royalties. The business behind it was later known as Publishing Life, and it now operates as Publishing.com. In 2026, its main program is AI Publishing Academy, which adds AI writing tools to the same self-publishing model.

Self-publishing is a real business, and some people do earn royalties from it. But in April 2026, Publishing.com and the twins agreed to pay $1.5 million to settle FTC charges over earnings claims, refund guarantees and testimonials. The same concerns had come up again and again: high total costs once ghostwriting, covers, ads and upsells are included, a refund guarantee with conditions, and heavily mixed customer feedback. Below we cover the history, the current offer, the costs and how it compares with a cheaper way to start an online business.

Who Are the Mikkelsen Twins?

Christian and Rasmus Mikkelsen are twin brothers. They were born in New Jersey in 1995, spent two years in Aarhus, Denmark, and moved back to New Jersey in 2015. They learned self-publishing through Stefan James's Project Life Mastery course before building their own business.

Their marketing highlights early success. The twins have claimed earning about $60,000 from audiobooks in 2018, and $53,000 from their first 100 course students. These figures are unverified. Amazon suspended Christian's account over poor-quality machine translation, and later Rasmus's account too. Their account was accessible again by 2023.

Net-worth figures online, which range from $20 million to $70 million per twin, are estimates with no public financial records behind them.

What the Course Teaches

The Original Audiobook Income Academy

The original course had seven modules:

1. Choosing a profitable nonfiction topic.
2. Planning and writing the book.
3. Hiring ghostwriters.
4. Email marketing.
5. Launching on Amazon.
6. Amazon Ads and audiobook narration through ACX.
7. Scaling to more titles.

It also included one-on-one coaching calls, weekly group sessions and a private Facebook group.

AI Publishing Academy (2026)

The current training has five modules covering mindset, the four parts of a book, AI-assisted outlining, ghostwriting, covers and formatting, reviews, copyright and Amazon Author Central. Students also get:

• Beta access to the company's AI writing software.
• Access to a team of ghostwriters (paid separately).
• Live group coaching five times per week.
• A private Facebook group of about 39,700 members.
• Bonuses including low-content book training, tax tips and the Audiobook Income Academy membership.

The AI software's mechanics are not publicly documented, so it cannot be evaluated before you buy.

How Much Does It Cost?

Pricing has changed over the years, and reported figures vary widely:

Audiobook Income Academy (low)$1,497

AI Publishing Academy$1,995

Audiobook Income Academy (high)$1,997

AI Publishing Academy$6,000

On top of the course fee, the model has production costs. Ghostwriting, cover design, editing, narration and Amazon ads all cost money for every book. Reedsy estimates that self-publishing a book typically costs $1,000 to $2,500. There are also upsells: one customer describes an $8,000 mentorship pitch, and another says they spent about $13,000 CAD across courses and coaching.

The Refund Guarantee

The program has advertised a one-year money-back guarantee. The FTC later alleged that this kind of "no questions asked" promise was undermined by conditions in the fine print (see below). It is "action-based," meaning you have to complete required steps to qualify. Some customers in 2022 described a 72-hour refund window, and one BBB complaint says refunds were limited to three days after payment. Several negative reviews, describe difficulty getting refunds.

With an action-based guarantee, ask for the exact conditions in writing before you buy, and keep records showing that you completed each step.

What Customers Say

The most common complaints are upsells, high total cost, pressure to buy mentorship, and a saturated Amazon market that needs ad spending to compete. Some Reddit users say they were removed from the Facebook group after posting criticism. Some critics allege that many Trustpilot reviews were encouraged with free coaching calls. We cannot verify that claim, but it is a good reason to read the low-star reviews as closely as the high ones.

Can You Really Make Money From Audiobooks and KDP?

Yes, but income is usually modest and uneven. A Written Word Media survey found that 63% of self-published KDP authors earned $1 to $500 a month, and Kindlepreneur estimates that about 5% earn more than $1,000 a month. Audiobook royalties through Audible range from roughly 25% to 40%, depending on the distribution option you choose.

Several factors make the model harder than the ads suggest:

• Competition: popular nonfiction niches are crowded, often by other students using the same method.
• Quality control: Amazon has removed books and suspended accounts over quality problems, including the twins' own early accounts.
• Upfront cost per title: each book costs money before it earns anything.
• AI content rules: Amazon asks publishers to disclose AI-generated content, and low-quality AI books face growing scrutiny.

How the Audiobook Model Works, Step by Step

The business model taught by the twins is easy to describe. Here is the typical sequence for one title:

1. Research a nonfiction niche with steady Amazon demand and beatable competition, such as a self-help or how-to topic.
2. Outline the book, then hire a ghostwriter or use AI-assisted tools to produce a draft, and edit it for quality.
3. Commission a cover, format the manuscript and publish the ebook and paperback on Amazon KDP.
4. Produce an audiobook through ACX, either paying a narrator upfront or splitting royalties with them.
5. Launch with reviews and Amazon Ads, then repeat with more titles to build a catalog.

Each step has a cost and a quality risk. A weak manuscript, cover or narration can sink a title, and ads can burn money before a book finds its audience. Students who do well with this model usually treat it like a small publishing company: they budget per title, track return on ad spend, and accept that some books will never earn back their costs.

ACX Royalty Options Explained

Audiobooks are distributed to Audible, Amazon and Apple through ACX, Amazon's audiobook marketplace. The royalty you receive depends on your choices:

• Exclusive distribution: a higher royalty (up to about 40%) in exchange for distributing only through ACX's channels.
• Non-exclusive distribution: a lower royalty (about 25%) but the freedom to sell the audiobook elsewhere.
• Royalty share with a narrator: no upfront narration fee, but you split royalties with the narrator, which reduces your share per sale.

The trade-off is between upfront cost and long-term income per sale. Paying a narrator upfront keeps your full share, but adds hundreds of dollars or more to the cost of each title.

Questions to Ask Before You Buy

• What is the full price today, and what exactly is included? Reported prices range from $1,995 to $6,000.
• What are the exact conditions of the one-year guarantee, and how do I prove I completed them?
• What will ghostwriting, covers and narration cost for my first three books?
• How much ad spend do students typically need before a book becomes profitable?
• What mentorship or upgrades will I be offered, and at what price?
• How does the course handle Amazon's AI disclosure rules and quality standards?

The 2026 FTC Settlement

In April 2026, the Federal Trade Commission announced charges and a proposed settlement against Publishing.com LLC, its CEO Christian Mikkelsen and its Chief Product Officer Rasmus Mikkelsen, according to the advertising law firm Frankfurt Kurnit. The case covered AI Publishing Academy, priced at up to $1,995, and the Publishing Accelerator coaching add-on launched in 2022. The FTC alleged that:

• Marketing claimed consumers could earn $1,000 to $3,000 a month in passive income, while most buyers never came close.
• A "no questions asked" money-back guarantee came with conditions in fine print that made refunds difficult or impossible.
• Testimonials were used without disclosing that some came from employees or relatives of the Mikkelsens, or were incentivized with cash, prizes or extra services, and some refunds were conditioned on giving positive testimonials.

To settle, Publishing.com and the Mikkelsens agreed to pay $1.5 million, and the FTC approved the final order in July 2026. The proposed order bans earnings claims without adequate substantiation, bans misrepresenting refund and cancellation terms, and requires clear disclosure of connections with endorsers and incentives for reviews. A settlement resolves the allegations without a trial, but it confirms long-standing concerns about earnings claims, refunds and testimonials.

Is Audiobook Income Academy a Scam?

We do not make legal findings. The twins "are not scammers," and the training covers a legitimate business model with live coaching. But in 2026 the FTC alleged false earnings claims, an illusory refund guarantee and undisclosed incentivized testimonials, and Publishing.com and the Mikkelsens paid $1.5 million to settle. That history should weigh heavily in any decision.

The problems are cost and expectations. Between the course fee, production costs, ads and upsells, the true cost of testing this model can run into several thousand dollars. And typical self-publishing income, according to author surveys, is far below what the marketing implies.

Pros and Cons

Who It Suits and Who Should Skip It

This model can suit someone who enjoys books, has a few thousand dollars to invest in production and ads, and is patient enough to build a catalog over time. It is a poor fit if you want a low-cost way to test online business, need income quickly, or would be financing the course.

Frequently Asked Questions

Our Verdict on Audiobook Income Academy

The Mikkelsen Twins teach a legitimate model, and Publishing.com offers plenty of live support. But the 2026 FTC settlement over earnings claims, refunds and testimonials is a serious red flag, and by the time you add a four-figure course fee, per-book production costs, ads and likely upsells, it is an expensive way to find out whether self-publishing suits you, and typical royalties are modest. If you are a beginner, consider our #1 recommendation for making money online first, and revisit publishing later if it still appeals.
