You missed on: None (they're all in the wrong place)<p>I don't actually know that of the last two, as I've never heard of them...but if you're not in Silicon Valley, you're probably in the wrong place for starting a tech startup that needs to raise money (and maybe the wrong place for any kind of tech startup...though there are other places where good tech talent is widely available, though maybe not as many willing to take a chance on working on equity-based compensation in a startup).<p>I actually think this applies to YC in Boston, as well. All of the startups that have started in Boston who wanted to continue have moved to the valley after the program.
Considering that all of these came up after YC, I'm not sure we can even assume these companies would exist without YC having first been created.<p>Granted I'm fairly certain someone would've conceived the YC model eventually.
