Most people see a street. He sees $300-600 per block. A 24-year-old from Chengdu figured out that every hotel, every apartment, every commercial space within walking distance is an untapped asset. One nobody has packaged yet. He straps a rig to his back, walks in, spends twenty minutes scanning the space, and leaves with a file that lets anyone on earth stand inside that room from their couch. The client pastes a link on their booking page. Guests tour the property before they arrive. Cancellations drop. Reviews go up. He gets paid $400 for the scan. $99 every month for hosting. The technology: 3D Gaussian Splatting. Free on GitHub since 2023. The app: Luma AI. Also free. The page he delivers: built by Claude in ten minutes. Total tool cost: $20/month. Month one: $3,500. Month six: $18,000. The streets haven't changed. He just started charging for them.
