Our team is nimble, intentionally lean, and embraces an ‘all hands on deck’ approach. We problem-solve with our partners when there are bumps in the road and look for opportunities to add value beyond financial resources.

Propel Capital was founded to use capital creatively for social impact.  

In 2008, sparked by a shared interest in cross-sector solutions to issues of inequality, we began working together to explore where we could have the most impact. Believing that investment capital could, in certain circumstances, be cycled repeatedly for social impact and that entrepreneurial approaches could help fuel innovation and drive social change, we began to make impact investments and grants to test our ideas and foster experimentation. We also shared the view that, if we could move quickly, with humility, a high tolerance for risk, and a willingness to let others take credit, we could do a lot of good in the world. And, finally, we shared the belief that we are all connected and, by concentrating resources and power in the hands of a few, our society starkly limits its future potential.

After some early experimentation, we launched Propel Capital to house this work and, from the beginning, decided that all Propel’s capital allocations – from operations, to the investment of the assets, to our grants would be in alignment with our values. To ensure that overhead was low and more resources flowed to organizations working on social impact, we established ourselves as a one of the first donor-advised funds at ImpactAssets (a mission-driven financial services company with $360 million in assets). In addition to using ImpactAssets to manage our grant and investment processing, we were intentional about prioritizing vendors and service providers who employ socially responsible business practices. Propel was one of the first philanthropic entities to invest 100% of our assets for impact and this early decision remains central to our mission today.

Starting in 2016, we scaled up our work – increasing our investing, funding, and staff capacity to work more closely with our partner organizations – and formed Propel Capital Network, LLC to enable a broader set of activities. Since we made our first grant, Propel has committed over $30 million to more than 30 social enterprises and impact funds working to create more inclusive economies, reform the criminal justice system, and innovate for a more just and equitable future.
