Amazon

Amazon's side hustle from Jeff Bezos's Seattle garage in 1994 outperforms #1 Apple in scalability, transforming from a books-only online store into a $1.7 trillion logistics and cloud-computing titan. Bezos personally drove packages in his Chevy Blazer to the post office, yet within 30 days of launch in July 1995, Amazon sold books to all 50 U.S. states and 45 countries—a customer reach 30% faster than the average e-commerce startup. The early focus on customer obsession, not profit, led to a 2,300% increase in sales from 1996 to 1997. By comparison, #4 Under Armour took 5 years to reach $10 million in revenue, while Amazon surpassed $1 billion in sales by 1998.
