Groupon is a social commerce company founded in 2008 in Chicago by Andrew Mason. It operates an online marketplace that offers daily deals for local businesses. Groupon's business model involves partnering with merchants to offer deep product or service discounts to consumers through daily deals. This provides a win-win situation for both merchants and customers, and fueled Groupon's initial rapid growth. However, the company now faces competition from rivals and some businesses are reluctant to work with Groupon again due to concerns about its discounts cannibalizing future sales.
