Andrew Mason and company could be poised to strike it rich.
The upstart group buying site is said to be valued at close to $25 billion ahead of an expected initial public offering.
The Chicago based e-business doesn't comment on plans to go public, but sources tell Bloomberg news that it has been in talks with banks about its IPO.
The $25 billion pricetag is a big leap from last year. In April 2010 the company was valued at $1.3 billion. Since then Groupon has raised more than $950 million in investments.
