The wonder man behind Groupon is 29 year old former music major Andrew Mason. Mason says the success behind Groupon is that it creates a win for both merchants and customers. Within a year Groupon has built a mailing list of 1.5 million names, sold more than 800 thousand Groupons, and has saved $35 million in 36 US cities. And it's not only food and shopping, Groupon can save you money on everything from museum memberships to skydiving. The company continues to grow at a rapid rate and recently turned down a $6 billion buyout from Google. Groupon recently raised $950 Million from investors.
