Fiscal sponsorship, in its various models, is a way to share various aspects of nonprofit infrastructure: corporate home, tax status, management team, policies, tech systems, etc. The sponsor is building its systems and management capacity to share with other programs and in doing so, both distributes costs and diversifies revenues. In this manner, fiscal sponsorship, as shared infrastructure, is a business model unto itself, both for projects and sponsors alike. We see hub organizations, such as alliances, associations, and the like adding fiscal sponsorship to their offerings to enhance both the mission-related support they offer constituents and their business models. Join us for a conversation around resource sharing as a business model for fiscal sponsors and other cooperative and collective organizations.
