Wave is a mobile service provider that allows unbanked people in Africa to access financial services such as saving and transferring money. Although Wave is a for-profit company, its founders—long-time members of the effective altruism community—launched it primarily with the goal of reducing global poverty.

As of February 2022, Wave is the largest mobile money service provider in Senegal.^[1]  Ben Kuhn, Wave's CTO, estimates that the company saves people in Senegal over $200 million every year—or around 1% of that country's GDP.^[2]
