It's not just about funding. I find being in Boston makes finding advisors, mentors, ents and domain experts really easy. You don't necessarily even need to be actively networking, you can learn tons 'passively' simply by attending meetups, events etc... While location shouldn't matter when it comes to the company itself, it makes significant difference in terms of getting access to a really powerful support network.

I completely agree. Your customers will be your best source of funding.
