How many non-board (or non-ex-board) members give to your arts organization?
How many non-staff members?
How many non-parents (if you do activities that include children)?
How many people who don’t attend your gala or other special event?
How many people who refuse donor benefits?
In other words, how many people donate simply based on your mission, programming, and activities; or by trusting a stakeholder of your mission, programming, and activities without expectation of a return?
Count the households of donors who donated all on their own. If the number is small, create a special campaign to draw them in, even if the donation is a simple $50. And thank them – they’re giving for no reason at all, except for unconditional love.
Ultimately, the health of your organization is measured by the number of those who unconditionally support it.
