Good Profit: How Creating Value for Others Built One of the World's Most Successful Companies is a 2015 book authored by Charles G. Koch, the chairman and CEO of Koch Industries. The book expands on Koch's concepts of virtuous capitalism and principled entrepreneurship, arguing that sustainable business success comes from generating 'good profit'—value created through innovations and services that customers freely endorse with their purchases. Koch contrasts this with 'bad profit' derived from coercive tactics or short-term gains, drawing from decades of experience managing Koch Industries into a global conglomerate. He emphasizes a bottom-up organizational culture that empowers employees to act entrepreneurially, discover customer needs, and contribute to societal well-being. Published by Crown Business in the United States (an imprint of Penguin Random House) and by Piatkus in the United Kingdom, the book serves as a guide for business leaders on implementing market-based management principles. Koch shares practical insights on talent development, decision-making, and long-term value creation, positioning the ideas as applicable beyond his own company to foster broader economic prosperity. It builds on his earlier work, 'The Science of Success,' and has been praised for its focus on ethical business practices while critiqued by some for promoting libertarian-leaning ideologies. The publication reflects Koch's influence in conservative and free-market circles, aligning with his broader efforts through organizations like the Institute for Humane Studies to promote individual liberty and limited government. While not an organization itself, the book's ideas have inspired discussions on corporate responsibility and capitalism's role in society.
