Trireme Partners LLP was a limited partnership venture capital company that invested in technology, goods, and services related to Homeland Security. The name "Trireme" was taken from a Greek warship designed with three banks of rowers.
Company principals included Richard Perle and Gerald Hillman. Trireme Partners was a Delaware entity registered in November 2001, two months after the September 11, 2001 attacks on the World Trade Center and the Pentagon. One of the firm's major investors was Boeing, who invested $20 million.
In March 2003, Perle became embroiled in controversy after The New Yorker published an article by Seymour Hersh. The article described a meeting between Perle, the arms dealer Adnan Khashoggi, and Saudi businessman Harb Zuhair, in which Perle allegedly offered to influence American foreign policy in Saudi Arabia in exchange for investment in Trireme. The U.S. Department of Defense Inspector General investigated the conflict of interest and determined that Perle did not violate the conflict of interest provision because he was only working eight days per annum at the Defense Department at the time, which was less than the 60 days of service requirement.
Trireme Partners completed its business and dissolved in 2005.
