The article above is specifically about VC-funded companies by definition. Nobody is arguing that you can’t be a successful entrepreneur outside of a startup hub. But if you’re going to play the “bubble metrics” game, raise VC, grow rapidly and exit for “bubble metrics” valuations, your odds are way higher if you move. Silicon Valley is generally full of young founders. They move before they have families. They couch-surf, eat ramen noodles and don’t let concern for a safety net impede possible success (however unlikely that is).
