Yes — and there is nothing stopping you from doing both. Giving and investing are completely separate transactions that serve different purposes. A charitable gift to the CFC-DAF funds the earliest-stage innovations with patient, mission-aligned capital. An investment in Cancer Fund I gives you a direct financial stake in a portfolio of those same innovations. Some members start by giving and explore investing later when they qualify. There is no required order, and no obligation to do both.
How does my contribution support cancer innovation?
Your contribution flows to early-stage cancer innovation through one of two paths. Charitable contributions go to the CANCER FUND Community Donor-Advised Fund (CFC-DAF) at ImpactAssets, which has deployed capital into Cancer Fund I, LLC. Cancer Fund I has made 14 investments across 10 portfolio companies working on therapies, diagnostics, and enabling technologies for cancer. Each investment is selected with input from our community of physicians, researchers, survivors, caregivers, and supporters — the people closest to cancer help decide where the capital goes.
