Third Sector Capital Partners, Inc. is a national nonprofit technical assistance organization advising our government agencies on how to reshape their policies, systems, and services toward better outcomes for all people, regardless of race, background, and circumstances. Founded in 2011, Third Sector is a 501(c)3 organization that has worked with more than 50 communities to deploy more than $1.8 billion of government resources toward outcomes. Third Sector's consulting engagements are organized into four Practice Areas - Economic Mobility, Early Childhood, Diversion and Reentry, and Behavioral Health - and help government agencies to better use data to understand the impact of their programs, improve the way they contract for services, allocate resources to support underserved populations, and collaborate with community stakeholders and partner agencies to improve services. Third Sector strives to co-create projects with our partners, understand the root causes of inequity, implement data-driven and community-driven solutions, and set up sustainable systems for continuous improvement to ensure that governments can do this work with their partners after their engagement with Third Sector ends.
