I moved from Amsterdam to Boulder, CO. The tech ecosystem is amazing here. It's crazy how many tech companies are in a tiny city with ~100k people. You just walk down the street and it's Nest, Google, Github, JumpCloud, SolidFire, Logrhythm, VictorOps and hundreds of smaller startups. Great ecosystem. People are friendly and welcoming. It's amazing, except the internet. It's expensive, unreliable, and slowwwww.
