The 4-Hour Workweek

What if you could run your business in four hours a day — and let AI handle everything else?

That's not a fantasy. It's an engineering problem. And this book is the solution.

The 4-Hour AI Workweek applies Tim Ferriss's legendary DEAL framework — Define, Eliminate, Automate, Liberate — to the AI tools and automation systems available right now in 2026. The result is a step-by-step blueprint for designing a business that generates serious income without demanding your constant presence.

Written by Jens Belner — former Canon Director, AI entrepreneur, and six-time Ironman triathlete operating from the Costa del Sol — this book combines twenty years of business leadership with hands-on experience building AI voice agents, workflow automation systems, and content machines that run while he's at the beach.

WHAT YOU'LL BUILD:

— A Freedom Number: the precise monthly income target that funds your ideal lifestyle, calculated from first principles

— An Elimination System: a structured audit that strips your working week of everything AI does better than you

— An AI Automation Stack: the five-layer infrastructure that handles lead capture, client communication, content production, and sales follow-up without human involvement

— An AI Receptionist: a 24/7 voice agent that answers calls, books appointments, qualifies leads, and sends follow-up summaries — for less than the cost of a gym membership

— A Content Factory: one weekly hour of your thinking, expanded by AI into newsletters, blog posts, and social media across five platforms

— A 90-Day Freedom Sprint: a week-by-week implementation plan that takes you from your current workload to a fully automated business infrastructure

INSIDE THE BOOK:

Part One — DEFINE: Calculate your Freedom Number, choose your AI-ready business model, and design your ideal working day with precision.

Part Two — ELIMINATE: Run the Elimination Audit, rebuild your relationship with email and meetings, and create the Async Operating Manual that protects your time.

Part Three — AUTOMATE: Build your automation stack layer by layer — workflow orchestration, AI voice reception, content on autopilot, and an AI sales machine that prospects, qualifies, nurtures, and follows up without you.

Part Four — LIBERATE: Apply geo-arbitrage to your income, structure the 4-hour working day, and make the shift from worker to architect of a compounding AI business.

Plus: Full AI Prompt Templates, a curated toolkit of 35+ tools with current pricing, real-world case studies with ROI calculations, and Appendix B — six ready-to-deploy prompt templates for the most common business automation scenarios.

This book is for consultants, coaches, therapists, agency owners, service providers, and independent professionals who are tired of trading hours for money in a world where the machines are willing to do it cheaper, faster, and without complaint.
