"Aucune astuce de croissance, idée marketing brillante ou équipe de vente ne peut vous sauver à long terme si vous n'avez pas un produit suffisamment bon"

Simplified Meaning:

If your product isn’t good enough, no amount of clever advertising, marketing tricks, or skilled salespeople can make it successful in the long run. Imagine you own a restaurant and serve food that tastes bad. Even if you have flashy ads and a friendly staff, people won't come back if the food isn't tasty. They might try it once because of your marketing, but they won’t return and tell others about it if the main offering—your food—disappoints them. This teaches that the foundation of any business is the quality of what you’re selling. For lasting success, focus on making sure your product or service is excellent. Good marketing can attract customers, but they will only stay if what you offer truly meets their needs and expectations. So, prioritizing the quality of your product should always come first when building your business.
