Though, the degree to which Groupon did is amazing. I can't believe any investor would have agreed to those terms. In the Groupon case as well, with 3000+ employees (which is, frankly insane), I don't know how anyone looking at the numbers, the terms, the business and the structure would have agreed to invest. Marketing be damned, unless someone blows this up it won't make money.
I'll never understand why they turned down $6B from Google.
