Comprehensive Guide to the Boulder / Denver Startup and Tech Scene

This post originally appeared on LeadOut Sales here.

Weekly, I’m asked to have coffee or meet up to talk about the Boulder/Denver startup and tech scene. I’m flattered beyond belief people reach out thinking I might be a good resource and am happy to live in such an open environment that believes in giving their time generously. This is something the Colorado community is known for and even has a #givefirst campaign.

In a lot of these meetings, I often repeat myself with the same resources, events and communities people should plug in to or support. Because I cannot meet with everyone right away, I wanted to create five solutions:

  1. This Comprehensive Guide to the Boulder and Denver Startup and Tech Scene.
  2. Join me at Boulder Open Coffee Club on the last every other Tuesday of the month at 8 am at Galvanize on Walnut.
  3. Join me at Caffeinated Mornings on the first Friday of the month at 9 am at Madelife.
  4. Participate with me at one of the many MeetUps or Events listed below throughout the year.
  5. Follow me on Twitter for the latest events, job openings, connections and occasional rants. Also follow the organizers or founders of these activities below as they are great resources, too!

This is just my list, but I know I’m missing quite a bit. Please feel free to comment and add your favorite way to get involved, and I can update the original source of this list periodically. Use this guide to help find a job, spend your sponsorship dollars wisely, look for partnerships, identify help for your startup, get published in media outlets, meet new friends and more. I’ll write a future post on personal branding and how to leverage this guide to get a job or elevate your brand in the community. But don’t wait for that — go ahead and get involved!

  • This is more skewed towards Boulder and heavy on tech and bicycles.
Denver and Boulder have two distinct flavors of startup and tech communities, yet are so close to each other there’s no reason to not be involved in both.
