Jeff Silver spent 15 years at American Backhaulers, a Chicago freight brokerage. When the company was sold, he wanted to try his hand at replicating its success. After earning a master's degree from MIT and an M.B.A. from the University of Michigan, Silver founded Coyote Logistics in 2006. The company specializes in fleet backhaul: using its customers' trucks to carry loads for other clients on return trips, so that fewer trucks travel empty. It has expanded its network by acquiring two companies. But Coyote owes most of its success, Silver says, to its intensive training program. He prefers to hire recent college graduates, who go through a two-month training program, then spend six months under the wing of a veteran employee. 'Before I started Coyote, I had people come to me and say, ‘American Backhaulers was the greatest company I've ever worked for,'' Silver says. 'We wanted to create that magic again.'
