Groupon has a proven model though. What the article is focusing on are the companies that haven't made large income or profitability. I assume the 20m example was probably from a company spending significantly more than that. Either way if a founder wanted to sell a large stake of shares, wouldn't that concern you to some extent that they saw an iceberg up ahead?
