What’s the secret to Silicon Valley? And can any other region nurture such a thriving startup scene? Linda Rottenberg, CEO of Endeavor, makes the case that a startup culture can be nurtured almost anywhere, so long as you have the raw ingredients — namely, a few initial entrepreneurs with access to capital and a willingness to pay it forward. Bear in mind that Silicon Valley is so much more than an archipelago of thriving tech companies. It’s actually an ecosystem — one that’s deeply  interconnected and self-reinforcing. Silicon Valley companies constantly swap talent — investors, entrepreneurs, hackers and managers  — as they grow from seedlings to huge proportions.  And any up-and-comer would have to do the same. Today,  no region can match Silicon Valley’s collective wisdom for scaling a business. But — from Buenos Aires to Boston, Tel Aviv to Shenzen — there are fledgling startup scenes that could ultimately give Silicon Valley a run for its money.
