With economic opportunity, sometimes it's making sure that if they're not in a place where they can have good jobs, that when they have economic opportunity, they have digital tools to use.

Make sure you continue to trust what you know now about yourself and stay true to what you believe in

Women around the world should have a tool that helps them plan their pregnancies.

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.

If we don't empower women, we don't allow them to unlock the potential of themselves and their children.

You can have the best vaccines for a woman or her child, but if you can't get her to come and get them then they won't work.

We start with an economic approach. We look at what are the greatest causes of death in the developing world, and what causes the largest amount of disability, which would prevent you from getting a job. A lot of those deaths start with diseases, diseases we don't get in such a great number in the United States.
