Kevin O'Leary says pioneers get slaughtered and settlers get rich. First to move well on a proven idea - and keep moving on it - may have the advantage. First to act? Not so much.
There are pros and cons to being first mover or second mover and examples of successes and failures of each. I prefer second mover, as someone else has de-risked, educated the market, etc. Now it's just to improve/differentiate, and capture market share (all things that are easier said than done!).
