One guy rolled a city-comparison spreadsheet he built for himself into a lifetime-membership digital nomad community — $20K/mo from a single product, the benchmark one-person company.
~40K members · $99 lifetime membership
It started with “solving your own problem” — a city-filtering spreadsheet he built for himself, casually posted to X, took off. The need was niche enough that nobody was serving it, but not so niche that nobody wanted it — and he was natively the expert.

Peter Levels is a Dutchman with no employees, no funding, and no team — one person, one laptop, roughly RMB 20M a year. Those are the figures a Bilibili creator relays from his four-hour interview with Lex Fridman and his 200-page founder handbook. His best-known product, NomadList, started about as ordinarily as it gets: he wanted to find cities that were cheap, had fast internet, and were livable, so he threw together a comparison spreadsheet of 25 cities listing the metrics he actually cared about — cost of living, internet speed, climate, safety. He casually posted that half-finished spreadsheet to X (Twitter) and it took off. Strangers kept adding cities and suggesting new metrics, and the demand snowballed. When the data outgrew a spreadsheet, he simply turned it into a website. Even the launch had a dramatic streak — a slip of the hand pushed a config to the server by mistake, the site went live unexpectedly early that day, and users submitted it to Product Hunt themselves, where it hit #1 for the day and top-5 all-time. Riding the momentum, he posted it to Hacker News, where it topped the front page to glowing reviews. Forbes covered it soon after, and Tim Ferriss (author of The 4-Hour Workweek) and WordPress's founder shared it — roughly 50,000 users with zero ad spend. From there it evolved from a city-filtering tool into a digital nomad community with a $99 lifetime membership. That one product alone now brings in around $20K a month from roughly 40,000 members.

Data credibility: A Bilibili creator relays Peter Levels's four-hour interview with Lex Fridman and his 200-page founder handbook: NomadList brings in roughly $20K/mo from about 40,000 members at a $99 lifetime membership, and Peter himself earns roughly RMB 20M a year. This is secondhand reporting about a public figure, not first-party evidence from the creator. All revenue figures are founder-reported or estimated by the video creator — unaudited.
Money landed on the first day and it was inbound. WordPress's founder emailed asking about hiring remote people, so Levels added a job listing slot to the page and charged against pageviews, which made the site profitable from day one without a single dollar of promotion.
The data loop came first and it was free labour: nomads looking up a city corrected and extended the city they had just left, which is how one spreadsheet became a database spanning more than 195 countries without a research team. The second loop is what made it a business.
The flat years came before NomadList, not after. His music channel had peaked near $8,000 a month and slid to $500, and at 27, in a Chiang Mai room costing $150 a month, he lay on the bed telling himself he was worthless.
