Overview
What they do
Founded by billionaire investor George Soros, the Open Society Foundations is one of the world's largest private funders of independent groups working for justice, democratic governance, and human rights. In 1997, OSF launched the Soros Economic Development Fund (SEDF) to harness the power of private capital for systemic change. SEDF is distinctive in the market for its "impact-first" philosophy; free from the constraints of commercial LPs, it provides highly risk-tolerant, catalytic capital to fragile and frontier markets where traditional investors hesitate. The firm leverages OSF's massive global footprint and policy expertise to support its portfolio companies and funds.
