💧 In 2008, one entrepreneur decided to sell bottled water, but the market was crowded with over 80 big brands like Evian, Perrier, Aquafina, and San Pellegrino, all spending billions on advertising.

Since he didn’t have money for marketing, he focused on getting people to talk about his product. He named his product Liquid Death and packaged it in a beer can. This surprised people and made them curious, leading them to share it with friends and try it out.

After 12 years of relying on word-of-mouth, Liquid Death overtook Evian in sales and is now worth over $1.5 billion.

"The more crowded the market, the more similar the brands become. My decision to stand out and do everything differently really paid off. Others couldn’t take such risks because of their reputations," said Mike Cesario.

The lesson here is simple: if you don’t have a lot of money, be bold and creative. You might get noticed, and people will start talking about you.

Have you heard of this water? I haven't, but the story is interesing 👍
