Since its founding in 1999, Zappos.com has grown to be the biggest online shoe store. Zappos uses a loyalty business model and relationship marketing. The company's rapid growth is attributable to repeat customers and numerous word-of-mouth recommendations. All corporate office employees, regardless of position, are required to undergo Zappos.com’s four-week Customer Loyalty Training course, which includes at least two weeks of talking on the phone with customers in the call center.
Zara is the flagship chain store of Inditex Group, owned by Spanish tycoon Amancio Ortega. The company is known for needing just two weeks to develop a new product and get it to stores, compared with a six-month industry average, and launches around 10,000 new designs each year. Zara has resisted the industry-wide trend towards transferring fast fashion production to low-cost countries.
