I recently graduated and my employer is allowing us to work remotely. I want to meet other techies and hopefully meet a potential co-founder. I was considering San Francisco, but since there's a pandemic, SF is less attractive and the housing costs don't seem worth it. I'm considering Denver now cause I can save a lot more and get a decent apartment, but I'm unsure what to expect with startup scene.
Boulder and Denver are close enough that you can really benefit from both. There aren't as many startups there as SF, but the people seem to be more interested in building relationships than just pushing their own app.
