MacKenzie Scott, novelist and ex-wife of Amazon CEO Jeff Bezos, revealed this week that she has given away more than $4.1 billion in the past four months to support people suffering the economic effects of the coronavirus pandemic.

On Tuesday, the billionaire published a Medium post noting she was inspired by the proliferation of community fridges, COVID relief funds, impromptu person-to-person Venmo gifts, viral debt relief campaigns, and mutual aid initiatives and asked a team of advisers to help her accelerate my 2020 giving.

Those advisers apparently used data to identify organizations with strong leadership teams and results, with special attention to those operating in communities facing high projected food insecurity, high measures of racial inequity, high local poverty rates, and low access to philanthropic capital.
