Everyone talks about first-mover advantage — the idea that getting to market first gives you an insurmountable lead. But the history of business repeatedly shows that first movers often lose. MySpace was before Facebook. Napster was before Spotify. Excite was before Google. The first company often creates the market and educates customers — and then gets surpassed by the company that arrived later but built it smarter, or saw something the pioneer missed. What matters is not being first. What matters is being the definitive version — the last significant mover. The company that improves so much on what came before that it becomes the standard.
