Better to Be Too Early to a Market Than Too Late

On the other hand, when you enter the market too early, you might have the "novelty" factor but it's really difficult to stay under the radar: clones show up fairly fast. So unless you are able to stay underground and still grow fast (improbable but not impossible), your early-to-market advantage is really not that big of a deal.
Finally, the size of the addressable market also plays a big role. A large market can easily support new companies that can execute better.
