Eight years ago, Travis Kalanick launched a startup called UberCab in San Francisco.
Today, Uber is a global behemoth and one of Silicon Valley's most successful companies — and one of the most contentious.
Uber operates in around 600 cities worldwide, and it's said to be worth nearly $70 billion.
The 40-year-old Kalanick is now said to have a net worth of more than $6 billion.

Kalanick got good grades and was athletic growing up, running track and playing football. But he was bullied by older students, and later vowed that he'd never be pushed around by anyone again.

Kalanick would eventually follow in the entrepreneurial footsteps of his mom, a retail advertiser: He went door-to-door as a teen, selling knives for Cutco. He then started his first business at 18, an SAT-prep course called New Way Academy.
