“Some foundations have switched to an ‘invitation only’ format, where they handpick the programs and organizations they want to fund. Some foundations have switched to a ‘Letter of Inquiry/Intent/Information’ approach. This helps the funder spend less time reviewing full grant applications complete with attachments about programs that are not a fit for their focus areas and it helps the grant applicants spend less time on a foundation that may not be a fit for their program.”
