All our staff are, in a sense, donors: most work at below the average non-profit salaries for our positions, and far below what they could earn in the for-profit sector, ensuring that The Seasteading Institute is financially efficient. Our thanks go to our entire team for their passion and dedication to the seasteading movement.
