You're lucky you got direct feedback. This is valuable intel. Educate your board and E.D. with it. Your nonprofit needs to have and proactively communicate how it is addressing deficit and why it got into it. A healthy net assets sum should be a comfort - if you have it. You got close to getting one funder to support you - return to them and ask for a referral to another they personally know well to get in door - or ahead of the que. Being 0 for 4 is not that unusual. Don't despair, but do decide if your best future is with this employer. Don't position your org. as seeking funds to handle a deficit. Yoru org. may not need some funding and a quick deficit fix, it may need a campaign.
