In San Francisco, there are now more cars dedicated to Uber than there were town cars before we launched, showing our growth in the market.

I'm Travis Kalanick, co-founder and CEO of Uber, and I do a lot of speaking because we're a technology company actively engaged in cities, with more than half of our employees located outside of San Francisco.

During my seven years at Uber, we expanded to 70 countries, completed 5 billion rider trips, and achieved a $70 billion valuation.

Uber is an app on your iPhone that helps you get a car, with the motto 'everyone's private driver.' You can see nearby cars and get notified when your driver arrives.

In cities like Boston, Toronto, Chicago, and San Francisco, Uber has expanded its services, including the introduction of Uber X, which is about 30% cheaper than traditional options.

Uber's strategy involves building a hybrid network of human drivers and autonomous vehicles to optimize resource utilization based on demand.

In San Francisco, our average pickup times improved from 12 minutes to around 5 minutes as more people began using Uber.

In the beginning, Uber was a lifestyle service for a select group of friends, requiring a special code to access the app, which led to explosive viral growth as users shared it with others.

My leadership has evolved significantly since Uber, where I learned from running a small team to managing thousands of employees and millions of drivers.
