Brian Acton quotes:

WhatsApp provides phone-number-based messaging, and people asked, 'Isn't that what SMS is?' Yes, but SMS is expensive, antiquated, and what WhatsApp did was modernize and level that playing field. For example, in Europe, if France wants to talk to Belgium, it's extraordinary costly because of border and telecom charges.

My mom started an air-freight company; my grandmother built a golf course. I have a certain degree of entrepreneurial risk-taking in my family history. Maybe that eventually rubbed off on me a little bit.

People want chat histories. They're a permanent testimony of a relationship.

Dealing with ads is depressing. You don't make anyone's life better by making advertisements work better.

Yes, I was a big math and computer geek, that's true. I was driven by the scholastic side of things. For me, it was all about what I could do with math and computers.

You have a certain identity that you present to the world on Facebook, and you have a certain identity that you present with the telephone, and they are different.

Dealing with ads is depressing. You donâ??t make anyoneâ??s life better by making advertisements work better.
