Frames growth as friction removal on both sides of the counter: 0% commission so owners keep all order revenue, no diner app or account (scan the table QR and order in any browser, menus auto-translated into 8 languages), and sub-5-minute phone-plus-OTP owner onboarding. Shows how each printed table QR becomes a product-led adoption loop, and how a free-until-2026 window plus orders-per-month pricing-after acts as a land-grab that monetizes only proven value (zero-order months always free, always 0% commission). - [DevTeam Korea](https://www.startupgrowthtactics.com/success-stories/devteam-korea): A productized-service growth case study on how DevTeam Korea (https://www.devteam.co.kr/), a Korean software studio that builds and operates MVP, web, app, and AI products end to end, escaped commodity dev-shop pricing by fusing development, web security, and post-launch digital marketing (SEO/AEO/GEO) into one accountable offering. Frames the bundle as a client-acquisition engine: a differentiated package the buyer cannot price-shop raises value per client; applying its own marketing capability to itself reached #1 on Google for Korean development keywords (e.g. "mvp 개발 업체"); and a rank -> win -> deliver -> refer authority loop compounded into dozens of major client contracts. No fabricated metrics beyond "#1 ranking" and "dozens of clients."
