Traditional growth is failing, but not because you aren't doing enough. The model itself is obsolete. In AI Marketing, Jason Y. Liu explores why the familiar "Marketing Funnel" has become a graveyard for companies in the age of intelligence. As AI takes over user judgment and attention becomes a scarce resource that can no longer be simply purchased, businesses must shift from a Traffic Economy to an Intent Economy. This book is not a collection of abstract concepts but a "Growth Operating System" (Growth OS) designed for the next decade of business. It provides an architectural blueprint for the Autonomous Enterprise, built on three core pillars: The Content Engine: Transitioning from artisanal handcrafting to an industrial-scale "Content Factory" using the original Talk to Create workflow. The Advertising Engine: Mastering the "Black Box" of algorithmic distribution through Signal Engineering and saturation testing. The Private-Domain Engine: Deploying AI Agents as super-salespeople to eliminate decision friction and automate trust-building 24/7. Featuring 12 specific AI Growth Playbooks derived from the practices of global giants like Amazon, Netflix, Coca-Cola, and Haier, this guide walks leaders through omnichannel dominance, GEO (Growth Engine Optimization), and the revolutionary shift toward A2A (Agent-to-Agent) Marketing. Whether you are a CMO looking to become a Growth Architect or an entrepreneur building a "Unicorn of One," this book is your survival manual for the dawn of the intelligent civilization
