The wealthiest entrepreneurs develop their business to serve lots of people. They fill an important need for a market that is wide enough to provide a substantial base, but still narrow enough to be specialized and distinctive. They look for ways to serve or impact the most people. If they're going to do it, they do it big. They put themselves in a business that can become ubiquitous. Otherwise, it is tough to have perceived value and scale upwards.
However, although they think big, they actually start small. They quietly refine their processes as quickly as possible and then expand as marketplace interest grows. By contrast, “wrong way” entrepreneurs want to start big. They seek lots of fanfare and venture capital early in the process. Most burn out because they could not ramp up with the increased attention and performance faltered as a result.
