Co-invest in community-led climate change.
Deep partnerships with donors, funders, and allies who believe in the power of community-led change form the backbone of our work. We partner to co-invest in a powerful network of high-impact community-led climate organizations, shifting power and influence to those leading solutions and change on the ground.
Connect with impact
Identify and connect with mission-aligned, high-impact grassroots climate organizations working across the country.
Direct resources with trust
Direct resources to where they are needed most, helping frontline communities and grassroots leaders meet both urgent and emergent needs with speed, agility, and trust.
Scale and influence
Scale impact and share insights, funding strategies, and lessons learned in order to influence others in philanthropy, and ultimately increase the flow of resources to frontline grassroots efforts.
If you are interested in co-investing in a powerful network of grassroots groups alongside TSP and our incredible community of donor and funder partners, please email our Development Team to explore opportunities to advance impact together.
