Being a sponsor means you provide a higher level of support in the form of a guarantee/collateral to ensure the nonprofit qualifies for a loan at an affordable interest rate. A private individual (such as a Board member or nonprofit leadership), or foundation can be a sponsor in one of two ways by providing collateral to back the loans or personal guarantee.
The Solidarity Loan provides a new way to sponsor a loan: guarantors can lend to at least 50% of the loan amount as subordinate debtors.
