WAM began in 2003 after women professionals in the microfinance industry, most of them based in Washington, DC, began meeting, at first informally in each others' homes. This growing group of WAM Founders came together to discuss areas of common concern, to decide if a more formal organization made sense, to explore what such an organization might do to support women who work in the microfinance industry and, ultimately, to support the development of the industry itself. After several months of planning and program design, WAM was formally launched in October 2003. Membership has grown steadily since.
