Companies in Silicon Valley invest a lot in understanding their users and what drives user engagement.

In 1991, I co-founded my first start-up, Ink Development, which made software for an early tablet computer.

I developed an interest in supporting independent journalists in a way that leverages their work to the greatest extent possible, all in support of the public interest.

Long-term sustainable change happens if people discover their own power.

When you have mass surveillance, it's impossible to meet the intent of the First Amendment because reporters can't talk to sources because sources are afraid to talk.

I have always been of the opinion that the right kind of journalism is a critical part of our democracy.

You can invest in companies, you can help grow companies, you can be a venture capitalist - and be a philanthropist at the same time.

I had the notion that, OK, so now we have all of this wealth, we could buy not only one expensive car, we could buy all of them. As soon as you realize that you could buy all of them, then none of them are particularly interesting or satisfying.

My dad was a physician. As a kid, I remember driving around with him on weekends so he could do his rounds at the hospital and talk to patients. We'd spend time in the car talking about what was going on with them, their stories.

In February of 1996, about six months after I created eBay, I started receiving a spate of complaints. Everyone was complaining about each other. I felt very much like I was a parent who had to adjudicate the brothers beating each other up.

Everyone is born equally capable but lacks equal opportunity.

A well-functioning microfinance bank can actually be a profitable business as well. So it became a perfect proof point that, through business, you can provide an experience that leads to individual self-empowerment.

Ebay's success as a company depends on the success of the community of sellers.

I'm a technologist by origin and by training, but I'm focused on philanthropy.

Advertisers don't want to put their ads next to the investigative story; it's extremely difficult to do that. And very few people today actually read those serious news stories on the Web now.

I do like to fly under the radar. When I walk around town, the only people I want to recognise me and call me by my name are the folks at Starbucks.

I had always been interested in markets - specifically, the theory that in financial markets, goods will trade at a fair value only when everyone has access to the same information.

What makes eBay successful - the real value and the real power at eBay - is the community. It's the buyers and sellers coming together and forming a marketplace.

What I'm really focused on is connecting people around shared interests, so together they can make good stuff happen. I'm more focused on helping people discover their power as individuals, but through those connections with one another.

If you give people the opportunity to do the right thing, you'll rarely be disappointed.

When I started eBay, it was a hobby, an experiment to see if people could use the Internet to be empowered through access to an efficient market. I actually wasn't thinking about it in terms of a social impact.

In the same way that you're driven in your business to keep innovating - Facebook is a wonderful example of constant innovation - think about doing that in philanthropy.

A lot of people don't just go ahead and try things.

In terms of my belief that one individual can make a difference - that belief comes from my parents.

Microfinance initiatives are very high-touch models. The loan officer meets with local groups of borrowers every week, they share tips and techniques. There's a lot of training and learning that goes on, which adds to the cost of the model.
