Nike has taken a minority stake in California-based Reflektion, an e-commerce start-up that uses analytics to predict shopping habits. Reflektion announced this week it has secured an $8 million series B round of venture capital for its technology that helps retailers personalize the online shopping experience for consumers. Intel Capital led the round, and Nike and several private investors also pitched in. At its investors' meeting last autumn, Nike said it expected its e-commerce business to be one of the company's biggest drivers of revenue growth in the coming years.
