This is usually found in markets that are growing quickly and full of competition (lots of companies are working on automated cars; most of them are actually car companies!). Don’t look for empty space and then be lonely; it is much better to use an innovative approach to become a player in a space that is or will be large. This may seem counterintuitive, since many entrepreneurs dream of entering “greenfield” markets that are brand new and have no competition. But usually there’s a reason the market is empty: It’s not big enough to sustain a growing venture.
