Evan Clark, Managing Editor at WWD, discusses the market debut of subscription-based personal style box company Stitch Fix on the NASDAQ. Evan discusses how impressive the company is, given that it was founded in 2011 and 6 years later was making nearly a billion dollars in revenue. We discuss the company's use of "data science" and whether the technology is enough to separate it from competitors like Amazon, which are launching similar services of their own. Clark adds that in order to keep up with competitors, Stitch Fix must continue to grow users by creating more services and offering more products. The company priced shares at $15 apiece Thursday night, below the expected IPO range of $18 to $20. It also cut the size of its offering from 10 million to 8 million shares.
