Many people think it's too late to start an Internet business, or it's too late to start a new billion dollar industry. The Innovation Stack is a guide towards not only the growth every business experiences as they deal with obstacles but also how to think about disruption. There are always new billion dollar businesses to start in every industry. There are always entrenched industries to disrupt. Jim McKelvey and Square did both. The Innovation Stack is a methodology and map towards navigating the constantly changing terrain of American entrepreneurship. We examine what it takes to navigate the constantly changing terrain of American entrepreneurship, learn to mitigate the risks, create new ideas, and new billion dollar businesses. It’s about the DNA of innovation, and the tools for anyone to succeed.
