Investing in a thriving planet, open to everyone.
Decarbon8 turns philanthropic capital into catalytic investments in early-stage companies building toward a thriving planet.
Decarbon8 is an impact fund that invests directly in early-stage companies. Investors use donations and grants to contribute, typically through their Donor Advised Fund (DAF). Entrepreneurs apply for funding and visibility.
Since 2020, we've backed companies across decarbonization, transportation, agriculture, built environment, renewable energy, and software.
In 2026, we're focused on Climate Resilience: Grid, Water, & Food. These are the systems that keep communities running as extreme heat, drought, and storms intensify.
Applications are currently closed for 2026. They will reopen for next year's fund in May 2027.
