Internet, Groupon Ipo | featured news

Groupon Inc's rapid growth has attracted rivals and regulators, a twin threat to the largest online daily deal company as it gets ready for an initial public offering.

Compared to Groupon, which has enormous administrative costs and is hemorrhaging a lot of money, Zynga is a ruthlessly-run, well-oiled machine.

Daily deals site Groupon Inc filed for an initial public offering, hoping to capitalize on the biggest investor stampede into Web start-ups since the dotcom bubble burst a decade ago.

Groupon is expected to pick Goldman Sachs and Morgan Stanley as its two lead underwriters for an IPO planned later this year. The IPO is expected to value the Chicago company at between $15 billion and $20 billion, these people said. The valuation could change depending on market conditions at the time of the IPO.
