Gary Cooper, 16, employs four staff selling mobile phones and gadgets on the internet, reports The Sun.
During the day he studies for four A-levels at Southend High School for Boys in Essex. But before and after lessons he runs his business.
Gary, who believes the firm will make its first £1million in a few years, pays himself £500 a month and is saving for a speedboat.
He said: "My staff look after day-to-day running. That leaves me free to oversee major items and get school work done."
Gary, from Benfleet, Essex, even has a deal with Southend United FC to put his firm's name GC's PCs on the scoreboard. (The Sun)
