Groupon user base hits 115 million

International group buying giant Groupon has hit the 115 million user mark, according to a new report from Reuters.

The report comes as a separate rumour from the Wall Street Journal claims that regulators are putting pressure on the company to remove a certain type of accounting metric from its IPO filing.

The Reuters report claims that Groupon has increased its user base from 50 million at the end of 2010 to 115 million. That figure is a 38% increase since March.

While much of Groupon’s growth is coming from international expansion, the publication claims that recent growth in users is not artificial as it has not bought as many companies recently.
