The Innovation Stack – How Crazy Ideas Create Unbeatable Businesses

Summary of the Book:

The Innovation Stack is a bold and insightful exploration of what it truly means to be an entrepreneur. Written by Jim McKelvey, cofounder of Square, the book tells the dramatic origin story of how Square disrupted the credit card industry—and beat Amazon at its own game. More than just a business memoir, it presents a powerful framework for innovation that any startup or founder can apply. Through humor, personal anecdotes, and historical case studies, McKelvey introduces the concept of an “Innovation Stack”—a series of interlocking innovations that build upon one another to form an uncopyable and resilient business.
