The Idea: Ernie Garcia III grew up around cars. In fact, his father owned DriveTime, a major used car dealership chain. But Ernie III didn’t want to inherit the family business; he wanted to disrupt it. He saw that people hated the traditional dealership experience: the haggling, the four-hour wait times, and the "trust me" vibe of used car salespeople. Teaming up with Ryan Keeton and Ben Huston, he pitched a radical concept: the "Amazon for cars." The thesis was simple but terrifyingly complex to execute - allow a customer to inspect a car in 360-degree HD, finance it, and buy it online in 10 minutes, with the car delivered to their driveway the next day. No dealer lots. No salesmen. Just an algorithm and a tow truck. This was the idea for Carvana.

The Execution:

All of which goes to prove that being a tech company isn't enough…eventually, you have to master the boring, gritty logistics of the real world to survive. Carvana nearly died by ignoring the fundamentals, but saved itself by mastering them.
