The company gives away 100% free bottled water by printing ads directly on the label. Brands pay for the ad space, and that revenue covers the cost of the water, bottling, and distribution. But there’s more to it than just free drinks. Every bottle helps fund the construction of water wells for people in need, creating a hybrid of advertising, sustainability, and philanthropy. It’s a bold new take on business: What if everyday essentials could be free — if someone else picked up the tab? @busine
