Denver, Colorado

It's not only the grass that's greener in Denver. Cool kids are flocking to the Mile High city for its more eco-conscious approach to tech, along with innovations in the cannabis industry. It doesn't hurt that it's also a haven for outdoorsy types who can hike and mountain bike nearby on the weekends. The entrepreneurial spirit is practically built in to the local government as well: Colorado's governor, Jared Polis, is the co-founder of successful seed accelerator Techstars. No wonder Salesforce, Google, and Facebook all have offices in town, with Palantir soon to follow.
