Successes:
* Tesla
Non-successes:
* Magic Leap
* Juicero
* Nuro
* Segway
What else am I missing? I suspect there are other successes that raised >$100mm pre-launch that I'm not thinking of.
I wonder why they wouldn't start smaller. That said, I still expect they'll succeed, and I hope they succeed. I don't believe in any rules of thumb, great startups always defy the odds.
