No it's not. It's over. There's no coming back from a $75M in debt at startup that makes no money with no end in sight. You'll need more investment. But who invests in companies that already owe huge debts and have terrible press? People that expect major ownership and a change in leadership, that's who. Or people that want to pick through the bones and pull out IP.
Maybe I'm wrong but if they get another infusion of cash, or make a profit in the next 3 years and bootstrap their way back, I'll be surprised.
