The only way to end poverty, to make it history, is to build viable systems on the ground that deliver critical and affordable goods and services to the poor, in ways that are financially sustainable and scaleable. If we do that, we really can make poverty history.

Poverty is too complex to be answered with a one-size-fits-all approach, and if there is any place that illustrates that complexity, as well as a better way forward, it is Rwanda.

I still feel that the kind of leader I want to be is one that spends time understanding our work in a way that allows me to translate it for policymakers and people who have real access to resources.

We need moral leadership and courage in our world.

I was encouraged to break all the rules but to take the best of philanthropy, the best of investing, and the best of development finance, and experiment with new ways to create this venture capital model of using philanthropy to back patient capital investments, and then build solutions that were measured in terms of the kind of impact and change they were making on people's lives and in the world, not just on the financial return.

Acumen Fund's patient capital investment in Western Seed is intended to enhance the food security and economic independence of Kenya's smallholder farmers.

I think we so often equate leadership with being experts - the leader is supposed to come in and fix things. But in this interconnected world we live in now, it's almost impossible for just one person to do that.
