What is it about certain business types that seem to restrict how much large they can grow?
For example, I've never heard of a large lawn-mowing corporation. Phone and computer repairers seem to consist mostly of 1 or two man operations. Wedding planners and photographers seem exclusively to be home businesses. Why is it that certain types of businesses seem never able to grow into a large company? I'm assuming if it were possible, at least some percentage of lucky or savvy businessmen or women would have found great success.
In the examples you have cited there are actually examples of large companies. Tree serives can be small businesses or part of a large chain. Pizza places ( Angelo's mom and pop place or Papa Johns. In many cases a lot of expansion is done via franchising
