In The Holdco Guide, Peter Kang distills the strategy, structure, and decision-making behind building a durable, multi-business holding company. Drawing from his work building Barrel Holdings, along with a wide study of leading holding companies across industries, Kang offers an accessible blueprint for designing a “holdco” that can grow, adapt, and endure.

Rather than relying on academic theory or Wall Street jargon, this book makes the mechanics of ownership, governance, incentives, and capital allocation practical for everyday operators. It shows how real-world holdcos—from decentralized software collectors to operational powerhouses—structure their systems, deploy cash, and lead teams to create lasting value across cycles.

Perfect for entrepreneurs, operator-investors, and leaders exploring multi-business ownership, this guide sits comfortably alongside The Outsiders, Buy Then Build, and books on Warren Buffett and Berkshire Hathaway as a foundational resource for strategic operators.

You’ll learn how to:

• Understand the core holdco archetypes—and how they behave across industries
• Design simple, durable structures for governance, incentives, and accountability
• Build capital pathways that support reinvestment, stability, and long-term growth
• Use FCF, ROIC, ROIIC, cash conversion, and other high-signal metrics to improve decision-making
• Ring-fence operational and financial risk to protect the entire system
• Evaluate opportunities across software, services, industrials, and other business categories
• Apply practical frameworks, examples, and workshop exercises to architect your own holdco

Clear, grounded, and immediately useful, The Holdco Guide helps founders and operators turn scattered ventures into coherent, resilient, high-performing systems built to last.
