How we built Warby Parker into a $1.8 billion eyewear brand

In 2010, Warby Parker disrupted the $150 billion global eyewear industry with a pair of $95 glasses. Started by four business school students, the pioneering direct-to-consumer eyewear brand has now sold millions of pairs of glasses, both online and in 269 brick-and-mortar stores across the U.S. and Canada. It brought in nearly $670 million in revenue last year, and currently boasts a market value of $1.8 billion.
