The book How to Make a Free Product Company dedicates an entire chapter to showing how everyday items — from tampons, seeds, coffee, and beer to EV charging and transportation — can become free or negatively priced using innovative business processes. It also explains that not all free products are equal: some, like water, reach everyone, while others, like diapers or apple juice, target specific audiences or offer longer ad exposure.

FreeWater, the world's first free beverage company wants companies like Coke, Pepsi, and Nestle to copy their business models.
