Digital village savings groups that guarantee loan repayment
Sudanese farmers face debtors' jail after a failed winter season left them unable to repay agricultural loans.
SanduqSafe digitizes traditional Sudanese Sanduq (village savings circles). Farmers form or join trusted groups that contribute weekly via mobile money. The pooled fund acts as collective insurance — if a member’s harvest fails, the group covers part of the loan repayment, preventing individual jail time. Includes financial literacy lessons timed to the winter planting calendar.
