One thing to keep in mind, with something like this, employees' stock is almost certainly worth $0. There will likely be some sort of retention plan for some set of employees, but their stock in GA probably won't be worth anything. The founders will likely have some sort of bonus, and the investors will make some money (not home-run money, but money). I guess they deserve a congrats, but to me it's worth remembering that most likely employees, who viewed their stock options as a part of their compensation, will be left with nothing but a thank you.
