BUILDING IN KOREA
Manballers Devlog — Episode 03
The Map Was Up. Now What About Money — and a Domain?
A Google Map on my screen felt like proof of something. Then Claude asked me two questions I hadn’t thought through at all: how does this make money, and who owns the name?
Once the map was actually running on my screen, the excitement lasted about a day. Then a much less exciting question showed up right behind it: could this ever make money? And if it could, did I need to protect it — a domain, a trademark — before someone else got there first?
I asked Claude both questions in the same conversation. The answers weren’t what I expected, and neither was the order they came in.
01
The Ad Revenue Math Nobody Tells You
The first idea I had was the obvious one: slap Google AdSense on the site and let it run. Free money, right?
Claude’s answer was blunt. With no traffic, ad revenue lands somewhere between 10,000 and 50,000 won a month — roughly $7 to $35. Not a typo. Not a business model. Barely coffee money.
Ad revenue is a traffic game, full stop. Without an audience already in place, no amount of clever placement or optimization changes the math. I’d been imagining passive income before I had a single active user.
02
Café SaaS — Closer, But Not Yet
The next idea felt more serious: a subscription model for cafés. Owners pay monthly — say 30,000 to 50,000 won — to customize their page, post events, reply to reviews, and see visitor stats.
In theory, this works. In practice, Claude pointed out the timing problem: a café owner pays when they’re already convinced that being listed brings in customers. With zero traffic, that conviction doesn’t exist yet. Nobody pays 10,000 won a month to be featured on a map nobody’s using.
It’s not a bad model. It’s a model for later — after there’s proof the map actually sends people through the door.
Lattes are a small market. If you’re building toward an exit, you need to aim at something bigger from day one.
03
The Line That Made Me Pivot
That one sentence from Claude did more than any spreadsheet could have. Latte Map wasn’t a bad idea — it was just a small one. A niche inside a niche. Even at full success, the ceiling was low.
That’s what pushed the pivot from Latte Map to Manballers. Barefoot walking is national in scope, naturally participatory — people want to check in, compare spots, share finds — and it already has an English-language identity through the wellness term “Earthing.” A Korean idea with a built-in bridge to an international audience.
04
What “Exit” Even Means at This Stage
Honestly, talking about an exit right now is premature. There’s no product yet, let alone users. But it helps to have a direction in mind, even a loose one.
If the location data grows into the thousands and monthly users into the tens of thousands, acquisition becomes a real conversation — a health and wellness app, a mapping platform, maybe even Kakao Map or Naver deciding it’s cheaper to buy than build. That’s a two-to-three-year horizon at the earliest, if it happens at all. But it’s the kind of ceiling that makes the current work feel worth doing properly.
Claude summed up the actual priority order simply: fans first, traffic first, revenue after. Not the order I would have guessed on my own — I’d have started with a pricing page.
05
Domain Name — Buy Now or Wait?
Once the site was live locally, a much smaller but equally new question came up: did I need to buy the domain right away?
Claude’s advice was direct: “Domains go to whoever buys first. Grab it early.” App name settled on Manballers, so manballers.com was the obvious pick.
Then came a side question — do domain and trademark need to happen together? Claude broke it down cleanly:
Domain
An internet address. First-come, first-served — buy early if you’re set on the name.
Trademark
Legal protection. Can be filed after the site exists — no rush the way there is with a domain.
I checked manballers.com on Namecheap. Available, about $12 a year — two coffees for the address to my idea. I hovered over the buy button and hesitated.
Nothing was finished yet. Would it still make sense to buy after launch? What if the direction shifted again, the way it already had once? In the end I held off. If I still feel sure after launch, I’ll buy it then.
06
Trademark — Korean First, English Later
Two versions were on the table: the Korean name and Manballers in English. Claude’s take: file the Korean trademark first, since this is a Korean service — the English version can wait until international expansion is actually on the table.
Cost breaks down clearly. Filing it myself runs 50,000 to 100,000 won. Using a patent attorney runs 500,000 to 1,000,000 won. Either way, examination takes one to one and a half years regardless of route.
Also not urgent right now. The site comes first.
07
Connecting a Domain Later — For Future Reference
Once there’s an actual domain to connect, Vercel handles it from its dashboard — enter the domain, then update the DNS settings over on Namecheap. Sounds technical, but Claude said Vercel walks through it step by step and it’s simpler than it looks. That’s a bridge for a future episode, once there’s something worth connecting a real domain to.
For now, the free vercel.app address is enough. I know that being first matters. I also know that right now, building the thing matters more.
