We seek social impact on four dimensions:Broadening Opportunity – We have a holistic understanding of poverty, so we invest across all facets of poverty: livelihoods, education, energy, health, housing, sanitation, and water.Deepening Inclusion – We invest at the edge of the market, emphasizing approaches that include people marginalized by depth of poverty, gender, and/or geography, including women and the rural poor.Serving Millions – We believe that every person matters, and want to expand opportunity for as many people as possible. We therefore focus on sustainable approaches that can, over time, scale to serve millions of people living in poverty.Improving Lives – We only invest where evidence convinces us that people living in poverty value the opportunity being delivered and are empowered by it – economically or otherwise – to improve their lives.
