Groupon, the group coupon buying site, is looking to raise a whopping $750 million with their initial IPO. One strategy Groupon in leveraging with this initiative is to incorporate a lot of banks to buy into the IPO, allowing them to spread the risk and access a wider range of expertise. Groupon established the group coupon buying concept when it launched in Chicago in 2009. Since then, an estimated 350 competitors have come to market. Names like LivingSocial and KGB Deals are among Groupon’s biggest competitors.
