Quick build-in-public note for this crowd. I started out building "a reading app." Somewhere along the way it turned into a **book marketplace** — a place where books get discovered, unlocked, and increasingly *created* by the people using it — and that shift changed almost every decision I made. Sharing the lessons in case you're building any kind of content marketplace. ## A marketplace has two sides, and you feel it immediately A reading app has one job: serve stories to readers. A marketplace has two constituencies whose interests you have to balance from day one — the people consuming the content and the people (or pipeline) producing it. The moment "write and publish your own book" became a feature, every catalog and discovery decision had to answer *both* "is this easy to read?" and "is this a fair place to be published?" That's a harder product, but it's a much stickier one. ## Discovery is the whole game On a single-creator reading app, you can hand-curate. In a marketplace, curation doesn't scale and pure chronological "newest first" buries everything good under everything new. The lesson I keep relearning: **discovery surfaces are the actual product.** Genre hubs, "continue reading," clear entry points into a catalog — these aren't decoration around the content, they *are* how a marketplace creates value. A great story nobody can find is worth exactly nothing to a reader or its author. We leaned into legible niches rather than a generic "all books" pile. A reader landing on a focused shelf — say romance, split into billionaire, CEO, and drama — can orient in seconds. You can see the shape of that in [the NanoReads library](https://nanoreads.com/hub): the catalog is organized as browsable hubs instead of one undifferentiated feed, precisely because discovery is where marketplaces live or die. ## Freemium-by-unit beat the paywall The monetization lesson that surprised me: a hard paywall up front kills a marketplace's top of funnel, but a *per-unit* unlock feels almost invisible. Letting readers start any story free and unlock the rest once they're hooked converts far better than asking for commitment before anyone's invested. People happily pay *after* they care, almost never before. For a two-sided marketplace that's doubly important — a free entry point is what keeps the reader side full enough to make the creator side worth it. ## The hardest part isn't supply — it's trust Once you make it easy to publish (in our case, with AI-assisted writing baked in), supply stops being the bottleneck. Quality and consistency become the bottleneck instead. Most of the unglamorous work is quality control: making sure the "write and publish" side doesn't flood the "discover and read" side with noise. A marketplace's reputation is set by its median item, not its best one — so the boring guardrails are the growth strategy. ## What I'd tell my earlier self If you're building a marketplace of any kind: obsess over discovery before you obsess over volume, make the first taste free, and treat quality control as a first-class feature rather than a moderation afterthought. The catalog is table stakes. The paths *into* the catalog are the product. Would genuinely love feedback from other marketplace builders here — especially on balancing open publishing against curation quality. How do you keep the median good without gatekeeping the whole thing?
