Best Advertising Agencies in Denver (2026)

Introduction

Denver has a compact advertising market built mostly on independent agencies, and the seven below cover TV, outdoor, radio and paid media work for Colorado and national clients. Several have been in the city for 35 years or more.

The client base reflects the Front Range economy: ski resorts and tourism boards, outdoor and craft beer brands, healthcare systems and a large share of public-health and state-agency work. Holding-company presence is limited, with Omnicom’s Integer in Lakewood the main network office. Recent changes include Karsh Hagan, founded in 1977, now operating as KHM alongside Arizona’s Madden, and Karsh Hagan’s “Protect Our Parks” taking Best of Show at the One Club’s 2025 Denver Awards.

Every agency here has an active Denver-area office in 2026. The list is unranked, since the right fit depends on your channels, budget and whether you need media buying under the same roof.

The best advertising agencies in Denver

1. KHM (Karsh Hagan)

Independent · Baker · khm.agency

Phil Karsh and Tom Hagan founded Karsh Hagan in Denver in 1977, and it now trades as KHM after combining with Madden, an agency started in Arizona in 1982. The group offers strategy, creative, media, technology and communications from its office on South Broadway. Its self-initiated “Protect Our Parks” campaign won Best of Show and three further Golds at the 2025 Denver Awards.

Tourism is the core of the roster, with Visit Denver, Aspen Snowmass and Travel South Dakota, alongside Denver International Airport, Litehouse Dressings + Dips and the University of Colorado Anschutz. Tourism boards running paid media alongside creative will find both handled in-house.

2. Cactus

Cactus has worked from Denver for more than 35 years and offers integrated strategy, creative and media. It is best known for Man Therapy, the men’s mental health campaign, whose “Shoot the Sh*t” work won a Gold for Integrated Branding Campaign at the 2025 Denver Awards.

Recent clients include Arapahoe Basin, Fjällräven, Smashburger, Odell Brewing, Cochlear and the North Carolina Education Lottery. Wright-Patt Credit Union recently named Cactus its integrated agency of record, and Wings Credit Union’s campaign ran through the Denver Broncos season.

3. Sukle Advertising + Design

Independent · Highlands · sukle.com

Sukle is a Highlands agency with a long record in public-interest advertising. It lists Ad Age’s 2026 Small Agency of the Year and Purpose-Led Agency of the Year honours, along with Platinum, Gold and Silver at the Graphis Advertising 2026 Awards. Its “Hairy Times” spot for the Wyoming Department of Health has won Best of Show at the Denver Awards.

Behaviour-change campaigns make up much of the work: Denver Water, the Wyoming Quitline, Generation Wild for Great Outdoors Colorado, and the Denver Climate Project. Commercial clients include Vail, Keystone, Purina, Whole Foods and Alpine Bank.

4. The Integer Group

Omnicom · Lakewood · integer.com

Integer is Omnicom’s commerce agency and works as the commerce arm of TBWA\Worldwide. Founded in 1993, it has its headquarters in Lakewood, west of Denver, and Built In Colorado puts its headcount at around 1,100, with about 350 locally.

The agency specialises in retail, shopper and e-commerce marketing for packaged goods, beverage, telecoms and automotive aftermarket clients. It is the strongest Denver-area option for brands that need in-store and retail media campaigns planned alongside national advertising.

5. Grit Advertising & Design

Independent · Highlands · madewithgrit.com

Grit is an advertising and design agency on Jason Street with its own studio, including a 20-foot cyc wall and video, photo and lighting kit. Founders left larger traditional agencies to start it, and the team runs a deliberately flat structure.

Beverage work dominates: Sierra Nevada (“1-800-HAZY” and “Still The One”), Arrowhead, Ozarka, Splash Refresher and Goose Island, plus Duke’s Shorty for Conagra. Its Sierra Nevada infomercial anthem and Goose Island packaging have both won at the Denver Awards.

6. Amélie Company

Independent · Denver · ameliecompany.com

Amélie Company is a full-service Denver agency covering campaigns, animation, media and web development. Most of its recent work is public-health advertising across outdoor, radio, social and video.

Campaigns include “Lift The Label”, which has addressed stigma around opioid and substance use disorders since 2018, “Keep The Party Safe” on fentanyl and naloxone, “I Matter” on youth mental health, and “Meet the Effects” on driving under the influence of marijuana. Its Recovery Cards Project for the Colorado Behavioral Health Administration won at the Denver Awards.

7. FiG Advertising + Marketing

Independent · Downtown · figadvertising.com

FiG is a Downtown Denver agency, with a second office in Chicago, that combines traditional services such as media buying, brand development and research with digital work across search, paid search, web and social. It also runs a sports marketing practice.

Work includes campaigns for the LA Kings and Chicago Fire, Whole Intent and redcup Beverage Service. The agency has won Platinum and Gold MarCom Awards. It suits mid-sized brands that want media buying and digital handled by one team.

What to look for in a Denver advertising agency

Decide first whether you need media buying in the same building. Most of the agencies above plan and buy media themselves, which keeps creative and placement decisions together. Others lean on production or media partners, which can work well if the hand-offs are clear.

Look at the sectors the agency already knows. Denver shops have deep experience in tourism, outdoor recreation, craft beer and public-health campaigns, and the Front Range has a large market for state and municipal work. An agency used to state procurement rules, or to seasonal ski and tourism calendars, will move faster on those briefs.

Ask how broadcast and video are produced. Some agencies have in-house studios or production partners, while others hire directors and post houses per job. Both are fine, but the cost structure is different, and you should see a recent spot made at your budget level.

Finally, check how the agency runs reviews and approvals. A TV campaign involves scripts, animatics, rough cuts, legal checks and versions for each platform, often across a client team that is not all in one office. Clear version control, one place for the latest cut, and a record of who approved what keep a campaign on schedule.

How Fabric helps advertising agency teams

Fabric gives an agency one workspace for files, client feedback and team knowledge, with AI search across all of it. The agency setup suits the way advertising accounts run: one space per client, with briefs, scripts, media plans, cuts and call notes kept together.

Broadcast and video files sit in Fabric’s cloud drive, which streams files on demand so they take no local disk space, and heavy files open without a full download. Audio and video transcription makes spots, radio reads and recorded calls searchable, and search works by meaning across documents, images and transcripts, jumping straight to the right page or timestamp. There is more on running commercial work this way in Fabric for commercial production teams.

For client review, any file or folder can be published as a web page and shared with password protection. Link analytics shows when each named recipient opened a link and how long they spent with it. Clients can leave threaded comments through a shared link without signing up. Commenters can also leave timestamped comments on video and draw on any video frame. The review and approval guide covers the full process.

On Team plans, self-writing docs keep a page for each client from meetings, Slack and the workspace, covering decisions, deliverables and open items.

Password protection and link analytics are included on Pro and Team plans, and self-writing docs on Team plans, which start from $125 a month. See plans for teams.
