Latest / Solopreneur Sessions with Fexingo: One-Person Businesses, Freelancing, and Independent Work / How a Solopreneur Built a Business on One Amazon KDP Niche
Transcript
- Lucas: Let me ask you something. When you hear the phrase 'publishing business,' what comes to mind? Luna: Probably a traditional publisher with editors, distribution deals, maybe a physical office. Or maybe a self-published author with a few books on Amazon. Lucas: Right. Now shrink that down to a single person, five titles, and every single product is a blank journal with a cute cover of a golden retriever on the front. Luna: Wait—like, literally just a notebook? No content inside? Lucas: Exactly. Low-content books. Amazon KDP category. And this one solopreneur—let's call her Sarah—is pulling in about four thousand two hundred dollars a month in royalties from those five journals. No ads. No social media. Just the Amazon algorithm. Luna: That's pretty remarkable. How did she even find that niche? Lucas: She started by browsing Amazon's 'Hot New Releases' in the journals section and noticed something. The top-selling notebooks had specific themes—gratitude journals, fitness trackers, meal planners. But there was a gap: pet owners. Specifically, golden retriever owners. There were a few options, but nothing that looked designed or professional. Luna: So she went after a very specific breed of dog owner. Not just 'dog mom' – but golden retriever specifically. Lucas: Precisely. And here's the clever part. She designed the covers herself using Canva—cost her nothing but time. Each journal is one hundred twenty pages, interior is blank or lightly lined. She set the price at $8.99. Amazon prints on demand, so she never holds inventory. Her royalty per sale is about $2.70 after Amazon's cut and printing cost. Luna: So if she's doing $4,200 a month, that's roughly 1,550 units sold per month. About 50 sales a day across five titles. Lucas: Right. And she didn't use any paid ads. Instead, she optimized the backend keywords and category selection. She listed each journal in two categories: one in 'Books > Journals & Notebooks' and another in 'Pet Supplies > Gifts for Dog Owners.' That dual-category placement let her rank for searches that competitors weren't targeting. Luna: So the Amazon algorithm essentially put her product in front of people browsing for pet gifts, not just notebooks. That's a clever arbitrage. Lucas: It is. And she didn't stop there. After the first two golden retriever journals took off, she expanded to 'Labrador Retriever' and 'French Bulldog'—but only two titles each. She tested smaller niches before scaling. The French Bulldog one did okay, but the Labrador one? Not as strong. So she dropped it after three months. Luna: She cut her losses fast. That's discipline. A lot of people would have kept trying to make it work. Lucas: Exactly. And here's where the economics get interesting. Her total upfront cost for each title was basically zero—just her time. She spent about three hours per cover design. No editing, no interior layout, no printing. So her marginal cost to launch a new title was just labor. Once a book is live, it takes maybe ten minutes a month to monitor sales and respond to customer questions. Luna: So she's essentially trading a few hours of design work for a potential stream of royalties that can last for years. But what about the risk? Lucas: That's the key question. She's entirely dependent on Amazon. If they change the algorithm, or if a competitor floods the category with similar designs, her revenue could drop significantly. She's already seeing some erosion. In month six, she was at $4,800. Now she's at $4,200. That's about a 12.5% decline. Luna: Is she doing anything to diversify? Lucas: She's exploring Etsy for the same products, and she's thinking about a simple website with a Shopify store. But her main focus right now is expanding to more breeds. She's testing 'Corgi' and 'German Shepherd' next. My hunch is that she needs to own the entire pet notebook space before competitors wake up. Luna: It reminds me of the classic 'platform risk' that every solopreneur faces. Whether it's Etsy, Amazon, or Upwork, you're building on someone else's land. Lucas: And that's the tension in this episode. She's built a solid, profitable micro-business with almost no capital. But it's fragile. The question for her—and for anyone listening—is how to capture the upside of a platform while building an escape hatch. Luna: Let's dig into the numbers a bit more. You mentioned the royalty per sale is $2.70. What's the breakdown? Lucas: Sure. Amazon KDP offers a 60% royalty for books priced between $2.99 and $9.99. So on an $8.99 journal, the gross royalty is $5.39. But then they subtract printing costs. For a black and white interior, 120 pages, the printing cost is about $2.15. On top of that, there's a delivery cost for digital files—about $0.15. So net royalty is $5.39 minus $2.30, which is $3.09. But she's based outside the U.S., so there's a small withholding tax. She nets about $2.70. Luna: And she's selling about 1,550 units a month. So her gross is around $13,900, but after Amazon's cut and printing, she takes home $4,200. That's about a 30% margin. Lucas: Yes, but remember, that's pure profit besides her time. She has no cost of goods, no storage, no ads. So her effective hourly rate, if she works maybe 15 hours a month on this, is about $280 an hour. Not bad for a side project. Luna: It's fascinating, but I wonder how replicable this is. The market for low-content books on Amazon is huge but also crowded. There are millions of notebooks and journals. Lucas: It's crowded in broad categories, but there are still micro-niches. The key is finding a combination of a passionate audience and a product that is under-served. For Sarah, it was golden retriever owners. For someone else, it could be 'bullet journals for left-handed people' or 'recipe journals for keto dieters.' The product is nearly the same—the differentiation is in the cover and the keywords. Luna: So the real skill is niche research, not design or writing. Lucas: Exactly. And that's something any solopreneur can learn. Sarah used a free tool called 'KDP Rock' to analyze search volume and competition. She looked for keywords with high search volume but few quality results. That's where she found 'golden retriever journal'—about 2,000 monthly searches on Amazon, but only a handful of products, most of which had cheap-looking covers. Luna: She saw an opportunity in the gap between supply and demand. That's the same principle behind any product-market fit, just on a very small scale. Lucas: Right. And once she identified the gap, she moved fast. She designed the first cover in a weekend and had it live within 48 hours. That speed is a huge advantage for solopreneurs—you don't need to run everything by a committee. Luna: And if it fails, you lose only a few hours of work. That's the beauty of a low-cost business model. Lucas: Which brings me to something I think about a lot with this show. If these conversations have moved your work forward in some small way—maybe you've tried a new approach or saved time on a decision—that's exactly why we do this. Listener support is what keeps it ad-free and focused on real stories. People who find value in the show sometimes chip in at buy me a coffee dot com slash fexingo. No pressure, just a quiet way to keep it going. Luna: Yeah, it's a small gesture that makes a big difference. And we genuinely appreciate it. Now, back to Sarah—I'm curious about the customer reviews. What do buyers say? Lucas: The reviews are surprisingly emotional. A lot of people say things like 'I bought this for my mom who just lost her golden retriever' or 'This is the perfect gift for a dog lover.' That tells me the product is connecting on a deeper level than just a notebook. It's a token of identity. Luna: So the niche isn't just about search volume—it's about tribalism. People identify strongly with their pet's breed. That's a powerful marketing insight. Lucas: Absolutely. And Sarah didn't set out to tap into that. She just noticed the gap. But once she saw the reviews, she leaned into it. She now includes a thank-you card in every package—well, Amazon handles the packaging, but she includes a digital insert that customers can print, with a note like 'Celebrate your golden moments.' It's a tiny brand touch. Luna: That's smart. Even on a platform like Amazon, you can inject a bit of personality. It differentiates you from the faceless competition. Lucas: And it likely drives repeat purchases. She told me that about 15% of her sales are from returning customers buying a second journal for a friend or a different cover. That's not huge, but it's organic growth without ads. Luna: What's the biggest challenge she faces now? Lucas: Competition. Since she launched, three other sellers have entered the 'golden retriever journal' niche. One copied her cover design almost exactly—same layout, different font. Amazon's brand registry helps, but it's not a perfect shield. So she's focused on speed: launching new breeds, improving her covers, and building a small email list through a freebie—a digital wallpaper of golden retrievers—to create a direct channel. Luna: That's the escape hatch we talked about. If Amazon gets too competitive, she can pivot to selling directly to her email list via a Shopify store. Lucas: Exactly. And that's the solopreneur playbook in a nutshell: use a platform to validate and grow fast, but always own the relationship with the customer. Sarah's email list is only 200 people, but that's 200 people she can reach without Amazon's cut. Luna: It's a micro-audience, but it's hers. I think that's the most important takeaway from her story. Lucas: Mine too. You can build a real business on a single platform niche, but you have to treat it as a starting point, not a destination. Sarah's now thinking about expanding into other pet-related products—maybe a 'dog walking log' or 'pet health tracker'—but using the same low-content model. Luna: So the strategy is to dominate one niche, then expand horizontally within the same audience. Lucas: Right. And she's doing it all with zero outside capital. That's the solopreneur dream, isn't it? A business that funds its own growth, run by one person, with the flexibility to pivot. Luna: It is. But it's also a reminder that the foundation is fragile. If Amazon changes their royalty structure or printing costs, her margins could vanish overnight. Lucas: True. But that's the same risk any solopreneur takes when they build on a platform. The smart ones plan for it. And Sarah is planning. She's already testing Etsy and considering a simple subscription box for dog lovers—a monthly curated journal and a treat. That would give her recurring revenue and a direct relationship. Luna: A subscription model would change the game entirely. Instead of chasing one-off sales, she'd have predictable income. Lucas: And that's the next frontier for her. But for now, she's focused on what's working: finding micro-niches, launching fast, and owning the customer relationship as much as she can within Amazon's walls. Luna: It's a great case study in focus and execution. One person, five products, a dog-loving audience, and a clear path to growth. Lucas: And a reminder that you don't need a million-dollar idea. Sometimes you just need a notebook with a golden retriever on the cover.
