Groupon said on its official blog on Friday that Margo Georgiadis was leaving the daily deals company to take a job as President of Google's Americas business.
"This change won't have an impact on operations," Groupon Chief Executive Officer Andrew Mason wrote in the blog posting.
He said that Groupon would reorganize its management structure in a way that reflects the company's evolving strategic priorities, with the Sales, Marketing, Channels and International divisions now reporting directly to Mason.
The news comes as Groupon is preparing to float shares to the public in a $750 million IPO.
Earlier this month, sources told Reuters that Groupon had put the IPO on hold for at least a few weeks, hoping to ride out global market turmoil while dealing with some regulatory scrutiny.
