In the past, many entrepreneurs chose to accumulate wealth in the private sector and become philanthropists later in life. However, now entrepreneurs can work to improve social issues through their businesses. Globally, a new business model has emerged that meshes businesses with governmental and social organizations. Nonprofits and businesses now team up to form a hybrid business model, led by a new generation of social entrepreneurs.
