This collection draws from 12 distinct company records with a recorded headquarters association in Colorado among the reviewed localities. This is a bounded source collection, not a complete census of businesses in the area. It shows 12 alphabetical examples, selected from the public founder reference library. The underlying headquarters statements come from the existing company source snapshot; administrative location records were reviewed on October 10, 2026. Known historical companies and headquarters statements marked as ended or deprecated are excluded. This is company-location research. It does not establish a founder’s residence, a present operating address, current employment, revenue, or an AE client relationship. The linked source records can change; confirm current details directly with the company. Numbers identify entries rather than rank business quality. ## Read the business context before reaching out. The entries include different activities, such as American architectural firm; AI implementation consultancy for U.S. small and mid-sized businesses; subsidiary of B:Side Capital, based in Denver and Phoenix; Independent outdoor gear retailer based in Denver, Colorado and Grand Rapids Michigan; American video game developer. Compare each company’s description, founding associations, and dated source material before treating two businesses as peers. A headquarters location can be useful for local research without defining the company’s customer footprint or where all its operations take place. - ## [4240 Architecture, Inc.](https://businessownerindex.com/company-reference/4240-architecture-inc-q136387380/) American architectural firm.
