Micro Equity Development Fund (MEDF) | 160 followers on LinkedIn. The Micro Equity Development Fund is a for-profit social enterprise that will provide micro-capital to small and medium businesses in developing countries in the form of equity and generate a return for investors while educating and empowering them with the knowledge to make their own informed investment decisions based on their self-determined personal risk profile. Micro-entrepreneurs and socially-conscious middle-class investors can begin to fill the so-called "missing middle" in developing economies, resulting in more profitable businesses for the poor and the potential to earn a reasonable return for the investor. Today, equity sources of capital are only available to one-billion people, and only those who can afford the fees of Investment Bankers.
