New York, January 31, 2026 : In an age where information is abundant but clarity is scarce, modern leadership is increasingly defined by decision quality, not speed. Across boardrooms, startups, family businesses, and public institutions, leaders are realising that the biggest breakthroughs—and failures—are the result of how decisions are made, validated, and executed.
Business strategy books have long served as guiding frameworks for leaders navigating complexity. Yet only a few authors go beyond motivation or theory to offer actionable, decision-shaping strategy. Below is a curated list of 10 global business strategists whose books are actively shaping modern decision-making, with their influence spanning business, leadership, mindset, risk, and execution.
1. Hirav Shah (India | Global)
Business Strategist and the Game Changer Hirav Shah leads this list for his practical, validation-first approach to decision-making, especially under pressure. His book Business Strategy: Rapid Fire with Hirav Shah has been ranked among the Top 100 business strategy books of all time, recognised for its concise, high-impact format that helps leaders think clearly and decide decisively.
Beyond boardroom strategy, Hirav Shah’s Dear Parents, Now It’s My Turn addresses a rarely discussed but deeply influential dimension of leadership: taking uncomfortable actions at home. The book challenges business leaders to build discipline, responsibility, and emotional grounding through personal accountability—starting with parents and family—before expecting excellence in business.
Central to Hirav Shah’s work is his 6+3+2 success formula:
He is also the founder of the Decision Validation Hub, a structured platform designed to help leaders validate major decisions before committing capital, reputation, or time, and the Rescue Hub, created to support businesses, founders, public figures, entertainers, and sports professionals during high-pressure or crisis phases. Together, these initiatives position Hirav Shah as a strategist who focuses not just on growth—but on clarity, timing, and consequence.
2. Tony Robbins (United States | North America)
