What we like to say is that the vision for Uber is the cross between lifestyle and logistics.

Uber exists because of mobile telephones.

Uber riders are the most affluent, influential people in their cities.

In many ways, we look at Uber as the safety net for a city.

At Uber, we say, 'Always be hustling.' Even if you are an introvert and you haven't got hustle in you, you better get a co-founder who does. And if you haven't got enough hustle to find a co-founder who's got hustle, it's going to be tough. You've got to have a little hustle in you.

Safety is number one at Uber... so we make sure the system is in place so riders get the safest ride possible.
