Iridium networks [0] initially launched with lots of capital and kind of only made it after stuff was sold at bankruptcy prices. Although I don’t think they are phenomenally successful.

I think there were a few dot coms that got bought out of bankruptcy by larger firms, maybe pets.com and toys.com (although toysrus is gone now).

Polaroid [1] too although I think that’s more branding than technology.
