Cohmad Securities was a US company whose main business was to introduce investors to the Bernard Madoff investment company for which it received commission based on the amount invested. The company, whose name combines “Cohn” and “Madoff,” was founded in 1985 by Bernard Madoff and Maurice Cohn, Madoff’s friend and former neighbor. Its office was located at the same address as Madoff's firm, and it employed between 10 and 20 employees with annual sales between $1M and $5M.
