A friend who supported himself through college on construction jobs, then went through a major surgery (think brain/heart/cancer) left his FAANG job for the startup.
His cofounders? A married couple with prime Bay Area real estate purchased by their family abroad, constantly bragged about Stanford (masters, mind you)and CCP connections.
Long story short, apparently the cofounder couple lied about their visa situation, both to the investors and to their cofounder. (They had a green card when they said otherwise). This was so they could lie about quitting their job at Google, which they never did.
My friend left when he found out, as he was the technical one anyway, and last I heard bootstrapped something with decent revenue.
In any case, the situation reminds me how important it is to fully vet your cofounders. Also, crazy that people can be effectively rewarded for being so scummy.
