It's really up to if the investors felt she defrauded them all. Some clearly do but others? It's not so clear to me. For whatever the reasons, she seems to be loved by at least a few investors, enough so that it puts dorks here on HN off.

Unicorn funding makes it a little different but I've worked with multiple CEOs that lost investors millions of dollars, had companies fail and then had the same investors bank roll them again. So long as the investors feel like they're running things the right way and communicating with them the right way, they appear to think a 40% hit ratio is stellar. Greed has a very limited memory. She'll take a break, probably get some sort of sweetheart deal either as a CEO or C-level officer of some small existing company in a different space (ad analytics or something, who knows?) and if they knock that out of the park, she'll be a champion again ready to get funding for whatever hot idea turns up. I also wouldn't be surprised to see her working at a VC firm.

If the DOJ swoops in and has charged, that would make things different.
