David Sacks demonstrates how the best startup founders talk about causes much bigger than themselves or the companies they're building. Google was about organizing the world's information. Tesla was about moving the world to sustainability, not just selling cars. These startup leaders saw a world that they wanted to create and built a movement around their visions. Sacks shows us how great startup products aren't just selling a product that solves an immediate problem; they are selling a vision of a better world that people can buy into. By doing this, they create MOVEMENTS; not just businesses.
