Many people look at growing a business as a task of how to reach the largest audience and make the most sales as quickly as possible. From my perspective, it takes time to grow a business and get a product or service out into the market. You can start big with lots of capital, or you can grassroots your product to a small group and let it manifest from there.
If you have capital, and can spend it, go for it. Venture capitalists and other investor types tend to introduce a lot of control and other issues if it’s something they take an interest in. Grassroots is the way most of us will either make it or break it in the marketplace.
