What it reported doing in 2025
KoukseonDO
Operating model
- Revenue model
- Mixed. Its operating money came from several sources; no one source provided a clear majority.
- Distribution model
- Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.
The verdict
STRONG - The filed numbers largely add up and a large share of available resources goes toward mission work. Total assets are small relative to annual expenses; liquid coverage is unknown and reported officer compensation is a large share of total spending, which may reflect staffing concentration.
