Seattle topped this year's list with its abundant resources for startups. The city's digital accessibility makes it one of the most ideal locations in the region for someone looking to jump-start an idea.

Our humble city of New York rounded out the top five with its ample number of universities and one of the largest bike-sharing initiatives in the world, Citi Bike. The list crosses the border after New York, featuring three Canadian metropolitan areas.
