Today, it is all different. We are all hyper-connected and the old barriers are much diminished. This means a founder in Silicon Valley, where the infrastructure is solid, can continue to do incredible things but, now, so too can founders everywhere. Yes, it can help to be geographically at the heart of it all but it is no longer an indispensable part of startup success.
I think Stripe's Atlas takes a huge additional step in helping to remove the accident of a founder's location from the list of barriers to entry in the world's startup club. I have explained my views in more detail here: https://news.ycombinator.com/item?id=11166417#11168750
And what a felicitous teaming between Patrick and Stripe to help further that goal. Great people all round, working to achieve great goals! I cannot imagine a better combination. Very exciting and congrats to all.
