I don't think they really know. The list of all LivingSocial filings is here: http://www.sec.gov/cgi-bin/browse-edgar?company=LivingSocial... and the $400M raise filing is here: http://www.sec.gov/Archives/edgar/data/1439606/0001439606110... which includes a note that $200M went to "others". But nobody seems to know definitively if those "others" included the founders or if it was just earlier investors cashing out. Given that the egregious cash out by GroupOn's founders had recently occurred I would be surprised if LivingSocial's investors would agree to paying off the founders but stranger things could happen.
