My background was computer science and business school, so eventually I worked my way up where I was running product groups - development, testing, marketing, user education.

Government funding that's coming from the United States is making a huge difference on the ground in the developing world. It's really palpable - it's making a huge difference saving lives.

I've travelled extensively in the last 16 years - to slums in Bangladesh, to townships in South Africa, to all kinds of places in India, etc. When I would go and talk to villagers about something like vaccines, if I stayed long enough, the women would bring the conversation around and say: "What about this family planning tool? We can't keep having the number of children we're having."

Any social or cultural change has to be made openly and with people agreeing. You don't get there by just pushing an outsider's point of view.

If you can't go to secondary school, the boys get to go and the girls don't, you're locked into a cycle of poverty, because you don't have a chance.

In the developing world, they don't have smartphones yet. They have the older plastic phones, but women are saving money on those, because they don't have access to banks. Having that access to digital money changes everything for her because she actually doesn't have to negotiate with her husband, which she will tell you is very hard in these circumstances, especially when the means are meager. She's expected to have money to pay for the kids' health or to help with the school fees.

Now we just really need to do the work, which we're doing, to get contraceptives out to women worldwide.
