Efraim Diveroli (born December 20, 1985) is an American former arms dealer and author. His company, AEY Inc., was a major weapons contractor for the U.S. Department of Defense. The U.S. government suspended AEY for violating its contract after AEY provided 42-year-old substandard and unserviceable Chinese ammunition and attempted to re-brand and re-package it, thus violating the American arms embargo against China. As a result of the publicity surrounding the contract and the age of the arms dealers – Diveroli was 21 and partner David Packouz was 25 when AEY landed the ammunition deal – the United States Army began a review of its contracting procedures.
Diveroli was sentenced to four years in federal prison. He is a central subject of the Todd Phillips dramedy film War Dogs, released in 2016. as well as a memoir written in conjunction with convicted fraudster Matthew Cox and published in 2016.
