Businesses in Colorado: a small-business state with 182,486 workplaces and a handful of big headquarters

This page is for anyone looking for Colorado businesses: people hunting for local suppliers or employers, analysts, and B2B sellers working the Front Range and the mountain towns. It covers the count and what makes Colorado's market different, the biggest headquarters, the counties and sectors, the state's open business register, and a worked example aimed at the firms that dominate the state.

How many businesses are in Colorado

In bands: 158,986 establishments with 1 to 19 employees, 19,792 with 20 to 99 and 3,708 with 100 or more. These are the Census Bureau's County Business Patterns (CBP) counts of business locations with paid employees, across all sectors, for the pay period including March 12, 2023. They leave out the self-employed and government.

Colorado has fewer establishments than Michigan (229,564) but they're smaller: 108,694 of them, 59.6%, have one to four employees, and only 161 have 1,000 or more. For a seller, that means a long list of small accounts where the owner or a general manager decides, and few large ones.

The biggest companies headquartered in Colorado

The largest SEC-registered public companies whose latest 10-K gives a Colorado principal executive office, by revenue in that filing:

Fiscal years ended in December 2025, except Pilgrim's Pride's (December 28, 2025) and VF's (March 28, 2026). Molson Coors' figure is net sales, after $1.90 billion of excise taxes; its sales before excise were $13.04 billion. Liberty Media's headcount combines 74 corporate staff with about 1,600 at its subsidiaries. Liberty Latin America, often listed as a Denver company, gives Hamilton, Bermuda on its 10-K cover, so it isn't ranked.

Two things stand out. Several are much bigger employers than their revenue suggests: DaVita reports about 78,000 teammates, 72% in the US, and Pilgrim's Pride over 63,000. And several are lean: Antero Resources produced $5.28 billion of revenue with 632 employees. Newmont adds a third pattern, reporting 26,600 contractors on top of its 17,500 employees.

Where Colorado businesses are

The nine Front Range counties above Mesa hold 75.9% of the state's establishments. In the mountains, workplaces are even smaller: Eagle County (Vail) has 3,664 establishments averaging 9.9 employees, and Garfield County 2,705 averaging 7.8. For the city itself, see companies in Denver.

What Colorado businesses do

Average pay and employees per site are our calculations from CBP payroll and counts. Professional services is the largest sector by establishments, and its firms average under nine people. Real estate has 14,354 establishments, almost as many as accommodation and food services. Mining and oil and gas pays the most per head.

Colorado's open business register

The Colorado Department of State publishes its entire business register, Business Entities in Colorado, on the state's open data portal. It covers corporations, LLCs and other entities registered since 1864, with each one's name, principal and mailing addresses, status, type, jurisdiction of formation, registered agent and formation date, and it was updated on 29 October 2026. It held 3,130,907 entities: 1,041,020 in good standing, 1,149,779 delinquent and the rest dissolved, withdrawn or revoked.

The register has no industry code, so use it to check a name you already have (is the entity in good standing, who is its agent) or to find recently formed entities in a city, and use Census data or a search tool to find businesses by industry. A delinquent status typically follows a missed periodic report rather than a closure, so check before you drop a prospect.

Prospecting Colorado's small professional firms

Accounting, law, engineering, architecture and consulting firms of 10 to 49 people are the sweet spot for many B2B services in Colorado: big enough to need outside help with IT, HR, insurance or marketing, too small to have a specialist on staff.

Illustrative example. The company, rates and results are fictional, to show the method.

Front Range Managed IT (frontrangeit.example) runs IT support and security for professional firms.

• Professional services establishments with 10 to 49 employees in Denver County: 408 + 324 = 732.
• Arapahoe adds 231 + 148 = 379, Jefferson 211 + 134 = 345 and Boulder 199 + 137 = 336, for 1,792 in all.
• It assumes 40% have no internal IT person: about 715 firms.
• Signing 2% a year would add about 14 clients.

It contacts the managing partner or office manager, not a technology buyer, and times outreach for lease renewals and office moves, when firms rethink their setup. Finding which of 1,792 firms fit takes research on each; Bebop can search for "Denver and Boulder accounting and engineering firms with 10 to 49 employees and no IT staff" and explain why each fits.

Subject: IT at [firm name] after the move

Hi [first name],

Firms your size usually have IT handled by whoever is most patient with the printer, which works until a laptop is stolen or a client asks for your security policy.

We look after IT and security for Denver accounting, law and engineering firms of 10 to 50 people, for a flat monthly fee per person. Could I send you a one-page checklist of what clients and insurers are asking firms like yours for this year?
