While the West obsessed over Amazon, a Japanese startup quietly built the world's most comprehensive price comparison engine. Kakaku.com doesn't sell products—it sells confidence. Every month, 70 million shoppers visit to verify they're making the smartest purchase decision.

"Kakaku.com doesn't compete with retailers—it makes them compete with each other, and captures value from the resulting transparency."

The revenue model is elegant in its simplicity: Kakaku.com monetizes attention without manipulating it. By aggregating prices, reviews, and rankings across every product category—from computers to fashion to food—they've become the indispensable middleman in Japan's e-commerce ecosystem. Their 132 employees generate $19.1M annually, a remarkable $145K per employee, proving that focused aggregation beats broad retail every time.

• Zero inventory risk: They never touch products, only information
• Hyper-local focus: 98.6% Japanese traffic creates cultural moats
• Trust as product: Users come for price, stay for verified reviews
• Multi-category dominance: From laptops to contact lenses
