Launched in November 2008, Groupon features a daily deal on the best stuff to do, see, eat, and buy in more than 500 markets and 45 countries—and soon beyond (hello, outer space). Groupon brings buyers and sellers together in a fun, collaborative way that offers consumers an unbeatable deal, and businesses many new customers. The company has accumulated more than tens of millions subscribers worldwide. Groupon was an unusual investment for us—we came in at a later stage.
