The One-Person AI Business is a practical guide for entrepreneurs who want to do more with less by building an AI-powered operating system around their business. Valeria Andros explains the shift from chatbots to generative AI, AI assistants, AI agents, and finally an AI workforce, showing how specialized systems can support research, marketing, content, sales, customer service, administration, analysis, and follow-up. Rather than presenting AI as a magical replacement for people, the book offers a balanced, credible approach: AI can perform multi-step work, but it still needs setup, permissions, monitoring, human review, and safeguards. Readers will learn how to identify the right tasks to automate, build their first AI agent, connect tools like ChatGPT, Claude, Gemini, Zapier, Make, and n8n, and design workflows that reclaim time without sacrificing control. With clear frameworks, real-world examples, and a 30-day transformation plan, this book helps solopreneurs, small-business owners, creators, and consultants build a modern business that can scale without a big team.
