With its relatively low cost of living and high quality of life, Colorado's capital city is fast becoming a small business hub. The 18th largest metro economy in America, with major sectors including energy, telecommunications and food, Denver boasts an impressive 47 companies on this year's Inc. 5000--not to mention that it's also a hotspot for the blooming marijuana industry.

Here's a curtain raiser to some of the top startups that have made the Mile High City their home:
