Ben Todd suggested last year that small donors might help organizations diversify their funding:
It’s also not healthy for an organisation to depend 100% on a single foundation for its funding. This means that until we have 3+ large foundations covering each organisation, small donors play a role in diversifying the funding base of large organisations. (Though note that you’re only providing this benefit if your grantmaking process is independent from the large donors.)
So... which organizations are looking for funding from small donors?
Open Philanthropy used to publish its suggestions, but their latest is from 2020. I imagine the funding landscape has changed since then.
