In early 2010, somewhere high above the northern hemisphere, Mark Krywko decided he’d had enough. The CEO of Sleek Audio, a purveyor of high-end earphones, Krywko was flying home to Florida after yet another frustrating visit to Dongguan, China, where a contract factory assembled the majority of his company’s products. He and his son, Jason, Sleek Audio’s cofounder, made the long trip every few months to troubleshoot quality flaws. Every time the Krywkos visited Dongguan, their Chinese partners assured them everything was under control. Those promises almost always proved empty.

As he whiled away the airborne hours, Krywko made a mental list of all the manufacturing glitches that had nearly wrecked his company. There was the entire shipment of 10,000 earphones that Sleek Audio had to discard because they were improperly welded, a mistake that cost the company millions. Then there were the delivery delays caused by the factory’s lackadaisical approach to deadlines, which forced the Krywkos to spend a fortune air-freighting products to the US. Even when orders were produced on schedule, Krywko wasn’t too pleased with the situation: The company always had precious cash tied up in inventory that took months to arrive after the prototypes had been approved.
