TSNE

TSNE is a Boston-based capacity building organization that partners with nonprofits so they have the financial, staffing and operational support needed to carry out their missions. It acts as a fiscal sponsor for mission-based projects, provides payroll, accounting and human resources services to small and mid-sized nonprofits, and offers spaces where nonprofits and communities can work, learn and collaborate. Equity sits at the center of its work, with a goal of a more just society.

The organization began as the Massachusetts Health Research Institute, founded by leaders from government and academia to serve as a fiscal sponsor for public and community health research and demonstration projects. That work revealed how many groups needed a solid financial and administrative foundation, and in the late 1990s it became Third Sector New England, broadening its mission to support nonprofits across the sector. It later shortened its name to TSNE.
