For a while, Groupon was the world's fastest-growing company.
When the company opened its offices in Korea just two and a half years after launching, it hired 300 people in a week by pulling them in off the street, The Telegraph reports. At the time the company had already expanded to more than 40 countries.
Last year, however, the company announced it would lay off 1,100 people and would close operations in seven countries.
When a company grows rapidly, it risks overshooting its needs, and may eventually be forced to make tough decisions. However, there are many successful companies that grow rapidly, hire aggressively, and then settle down.
