Amazon

American technology and commerce company founded by Jeff Bezos in 1994 as an online bookstore that became the world's largest e-commerce company, the dominant cloud infrastructure provider, and a major media, AI, and logistics company.

Invented the flywheel model — lower prices attract customers, customers attract sellers, sellers fund infrastructure, infrastructure lowers costs — and funded it with AWS's cash generation, allowing indefinite reinvestment in customer experience at scale.
