A first-mover advantage refers to the benefits a company gains from being the first to enter a market or exploit a niche. This allows the company to establish brand recognition, build customer loyalty, and capture a larger market share before competitors enter. Making improvements to existing product lines, taking risks to improve an existing market, and poaching trained personnel from an established business may provide strategic advantages but do not necessarily constitute a first-mover advantage. Taking a free-ride on the opportunity created by a pioneer would not be considered ethical or sustainable business practice.
