Overview
Mission
We are a coral reef conservation research institute dedicated to providing services that will help save coral reefs. Unfortunately, we went with the "you've gotta spend money to make money" approach, whereby we did primarily pro bono consulting work. This led to approximately a ~$14,000 net loss in income over the course of the year. We did secure a $5,000 award to help with analysis of marine biology data (data analysis being amongst our core serfices).
What it reported doing in 2025
We conducted a number of coral reef field surveys pro bono to help developing countries manage their coral reefs: Mauritius, Mexico, and several others. I am hoping this "spend money to make money" approach (good karma) will help get for-pay survey and diagnostic contracts in 2026 and beyond.
Operating model
- Revenue model
- Earned-program. 100% of the money available for current operations came from fees and other program revenue.
- Distribution model
- Direct operator. The filing allocates 99% 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 - A large share of available resources goes toward mission work and the filed numbers largely add up. Expenses are high relative to revenue and total assets are small relative to annual expenses; liquid coverage is unknown.
