Mission & Values

Our mission is to accelerate America’s transition to a performance-driven social sector.

About Us

Third Sector Capital Partners, a 501(c)3 nonprofit advisory firm, has a seven-year track record of collaborating deeply with communities to re-write how they contract for social services, re-aligning vast amounts of public resources to move the needle on social problems. We have helped launch ten outcomes-oriented contracts that transition over $360 million in total public funding towards positive outcomes.

Third Sector uses contracting and finance incentives to align diverse funding streams with social impact in communities across the United States. The Third Sector team brings extensive experience managing projects with diverse groups of stakeholders, economic modeling, fundraising, impact investing, evaluation, and data analysis.

We have engaged with more than 40 jurisdictions across the country in developing and deploying outcomes-oriented strategies to align resources with results for communities. We are strengthening the pipeline of state and local governments and service providers prepared to implement Pay for Success projects as well as creating opportunities for communities to better measure and evaluate the success of their social service programs.

Third Sector is supported through a range of philanthropic and government sources, including a grant from the Corporation for National and Community Service’s Social Innovation Fund. We have offices in Boston, MA, San Francisco, CA, and Washington, DC, and serve clients across the United States. Learn more about our team.

Our Values


We have respect for our clients, for the people whose lives we aim to improve, and for the hard work that has and is being done to move toward a performance-driven social sector.


We will bring an intellectual and analytical rigor to our engagements, to help clients engage with Pay for Success and its potential to advance effective and proven programs.


We bring deep experience in finance, project management, and evaluation, but recognize the value of learning from and collaborating with partners at all stages of a project.


We believe in developing projects that measurably improve the lives of people in need and creating a sustainable field that funds programs with demonstrated impact and results.
