The private-nonprofit partnership model of social enterprise is a mutually beneficial business partnership or joint venture between a for-profit company and a nonprofit organization. The partnership may occur with an existing social enterprise, or may result in the creation of a new entity or a profit center. The social enterprise may or may not be mission-related and leverages the nonprofit organization's assets, such as relationships with their target population, community, brand, or expertise. For the for-profit, the partnership yields one or more of the following benefits: lowers costs (cheaper labor/lower R&D costs); reduces restrictions (no strict regulatory oversight); improves community relations or public image; enables new product development; penetrates new markets; or increases sales. Partnership benefits for the nonprofit are financial return, marketing and brand equity, and in cases where the activity is mission-related, social impact. The market is most often external--the public, but examples exist where the paying customer and the client are one. The private-nonprofit relationship may be structured as a joint venture, a licensing agreement, or formal partnership.
