Disease foundations and philanthropic funders
A real market with no map. Liver disease, hepatitis and cancer foundations, family offices with a personal reason, and corporate giving programs all fund work like this, and none of them are listed anywhere by what they actually care about. Said plainly rather than dressed up: this group is reached by name and by program, never by list.
Who signs: program officer, executive director, head of research grants, and at family offices the principal.
No register by disease area
identified one at a time from published grants and program pages; the difficulty is the reason the segment stays open
