Do you have an example for such a startup in recent history where the founder left within the first few years and the startup succeeded with a new founder? I don't think we can really value Uber at $70B; that's the headline number for investors getting preferred shares. My main point is that Uber's position is not nearly as strong as the $70B implies; this number exists because Travis was super aggressive at growing revenue, so investors must have had expectations of the company continuing its insane growth trajectory. I don't believe Uber has that strong a moat today, and the leaked numbers imply losses left and right.
