Marketing is expensive because most agencies still do the mechanical half by hand, and a retainer bills for those hours. "Agents now build the campaign, segment the audience, draft the copy, and stage the send. The marketer is the director, not the operator." That is what I rank for below. The metro counts, so Englewood, Glendale and Lafayette firms are here. If you also need a lifecycle email specialist, see the best email marketing agencies in Denver.
1. Adswerve
1Adswerve
Anika Schmidt, Sr Director, Product & Design, Adswerve
- Best for
- Measurement, modeling and AI on the Google and Adobe stack
- Location
- Headquarters at 1700 Broadway, Suite 850, downtown Denver, with 30 staff located in Denver or Boulder on LinkedIn
- Platforms
- Google Marketing Partner, Google Cloud, Adobe Solution Partner
- AI stack
- Google Meridian, Vertex AI, Gemini, Looker
A data and media consultancy building AI on a client's own data. For Six Flags it built a pipeline that translates social comments, scores sentiment and has generative AI write a weekly summary of the top five positive and negative trends in a Looker dashboard. Its custom marketing mix model for Alaska Airlines runs on Google's open-source Meridian, and Adswerve credits it with $100M in revenue potential. A custom bidding script cut Betterment's CPA by 10% in a test against fixed and Google-automated bidding.
My view is that platform-reported revenue cannot be trusted: at Bluethumb, what Meta, Google and Klaviyo attributed to themselves added up to about three times actual sales, so a model built on your own data earns its fee. The headquarters is at 1700 Broadway, Suite 850, and 30 staff are located in Denver or Boulder on LinkedIn.
The pick for measurement and AI built on your own first-party data, from a firm headquartered in downtown Denver.
2. Digible
2Digible
Reid Wicoff, Founding Partner, CEO, Digible
- Best for
- Multifamily marketing with in-house AI tools
- Location
- 3400 S. Broadway, Suite 140, Englewood, with 53 staff located in Denver or Boulder on LinkedIn
- Platforms
- Google Premier Partner, Meta Business Partner
- AI stack
- Fiona (in-house), FionaCalls (in-house), Fiona Fair Housing Compliance (in-house), Fiona Google Business AI Posts (in-house)
Multifamily only, with a suite of in-house tools to match. FionaCalls transcribes every inbound call and labels it Lead, Missed Call or Not a Lead, and Digible reports a 27% average lease-opportunity rate over the last year. Its fair-housing scanner checked 46,134 items across 2,535 properties and flagged 10% for issues, and a third Fiona tool automates daily Google Business Profile posts for apartment communities. Those figures describe the tools, not a client outcome. For one, a Performance Max restructure for Freeman Webb lifted CTR 15% and cut CPC 16% to $0.93.
My view is that the agencies spinning up their own tools, a handful of which Nitrosend already serves, are the ones to watch. Digible works from 3400 S. Broadway in Englewood, with 53 staff located in Denver or Boulder on LinkedIn, among them founding partner and CEO Reid Wicoff.
The pick for apartment communities, with in-house automation no generalist agency matches.
3. DEPT
3DEPT
Jesse Stevens, Group Director, Client Partner, AI, DEPT
- Best for
- Enterprise AI builds, commerce and marketing
- Location
- 3320 Walnut St, Denver, one office of a global network, with 41 staff located in Denver or Boulder on LinkedIn
- Platforms
- Adobe, Google, Salesforce, Shopify
- AI stack
- Adobe GenStudio for Performance Marketing, ChatGPT apps
A global network with a named AI practice, and one caveat that matters: its AI proof was delivered elsewhere. DEPT designed and built Healthdirect's clinically grounded health-guidance app inside ChatGPT, work by its Australian team. It launched an accelerator built on Adobe GenStudio for Performance Marketing, which it pitches as bridging AI's execution gap.
The Denver office is at 3320 Walnut St, and 41 staff are located in Denver or Boulder on LinkedIn, including Jesse Stevens, a group director and client partner for AI. The services menu runs from brand and media to commerce platforms and AI transformation, so the fit is an enterprise that wants AI product builds, commerce and marketing under one contract. A small or mid-size brand will pay for scope it does not use.
The enterprise pick when you want AI product builds and marketing from one network with a Denver office.
4. Wpromote
4Wpromote
Jessica Mainelli, VP, Managing Director, Wpromote
- Best for
- Full-funnel media with a proprietary AI platform
- Location
- Headquartered in El Segundo, California, with 16 staff located in Denver or Boulder on LinkedIn; no Denver street address published
- Platforms
- Google Premier Partner, Microsoft Elite Partner, Amazon Ads Advanced Partner, The Trade Desk Premier Partner
- AI stack
- Polaris IQ
A national firm headquartered in El Segundo, California, with a real Denver team and no Denver street address. Polaris IQ, its proprietary platform, supplies what Wpromote calls AI-powered insights across creative, media and measurement, and its AI search service tracks how often a brand appears in answers from the major LLMs across about 300 prompts and 15 topics. Both are platform claims, with no client result tied to them on those pages.
Denver appears as a preferred office on its contact form, and 16 staff are located in Denver or Boulder on LinkedIn, including VP and Managing Director Jessica Mainelli. It also ranks on the Los Angeles and Chicago lists. It suits a mid-market or enterprise consumer brand spending across many channels that wants full-funnel media and one reporting layer, run by a Denver team.
The pick for full-funnel media at scale, run by a Denver team on a national firm's platform.
5. Location3
5Location3
Alex Porter, CEO, Location3
- Best for
- Franchise and multi-location marketing
- Location
- 720 S. Colorado Blvd., Suite 462-S, Glendale, with 18 staff located in Denver or Boulder on LinkedIn
- AI stack
- LOCALACT (in-house)
Franchise and multi-location marketing, run from Glendale. LOCALACT, its in-house local platform, supplies the AI-powered technology, campaign execution, reporting and local advisement for each franchise location, though the page names no model or workflow. The results carry more weight. For Mathnasium, lead volume rose 16% year over year on a 2% budget increase and cost per lead fell 12%, using machine learning plus account management across search, social and retargeting.
A Wild Birds Unlimited connected-TV campaign with algorithmic bid optimization logged 9.3MM spot views, 4,747 QR-code scans and 289 on-site conversions, and Interstate All Battery Center store visits almost doubled in 6 months while cost per result fell 29%. The office is at 720 S. Colorado Blvd., Suite 462-S, with 18 staff located in Denver or Boulder on LinkedIn, among them CEO Alex Porter.
The pick for franchise and multi-location brands.
6. Two Octobers
6Two Octobers
Nico Brooks, Principal, Two Octobers
- Best for
- B2B analytics and paid media with AI-assisted analysis
- Location
- 1001 Bannock Street, Suite 120, Denver, with 7 staff located in Denver or Boulder on LinkedIn
- AI stack
- Treeline Intelligence (in-house)
The most careful AI design in Denver. Treeline Intelligence, its in-house platform, runs data retrieval, calculations and statistical checks in code while AI drafts the analysis across thousands of data points under an analyst's direction, which keeps the model away from the arithmetic it gets wrong. No client number is tied to Treeline yet, and the FINE Design Group result, thousands saved a year in Google Cloud fees and 50% faster responses to data requests, came from an analytics build, not AI. For AgentSync, MQLs rose 18% at a lower cost per lead.
It publishes its floor: paid media management fees start at $1,000 a month. It describes itself as a Certified B Corp, works from 1001 Bannock Street, and has 7 staff located in Denver or Boulder on LinkedIn, including Principal Nico Brooks.
The pick for B2B analytics, with AI kept away from the arithmetic.
7. Booyah Advertising
7Booyah Advertising
Troy Lerner, CEO, Booyah Advertising
- Best for
- Paid media with platform-AI bidding
- Location
- 1700 Lincoln St, 46th Floor, Denver, with 47 staff located in Denver or Boulder on LinkedIn
- AI stack
- DV Scibids AI, Search Ads 360 auction-time bidding
A large Denver media agency whose AI is ad-platform tooling, with the numbers published. Booyah grew Bona's social reach 33% using DV's Scibids AI bidding, and Search Ads 360 auction-time bidding drove 46% more paid-search registrations for Dice.com. It cut Ria Money Transfer's CPA 23% despite Meta's special-ads targeting limits, and Charlie's Soap saw a 138% market-share increase on Instacart.
None of that is automation Booyah built itself. It works from the 46th floor of 1700 Lincoln St, with 47 staff located in Denver or Boulder on LinkedIn, including CEO Troy Lerner. It suits a consumer or lead-generation brand that wants paid search, social and programmatic from one established local team. The booyahadvertising.com site is the same firm.
The pick for paid media from a large Denver team.
8. Fruition
8Fruition
Brad Anderson, Founder, Fruition
- Best for
- AI platform builds plus SEO and paid media
- Location
- States a Denver office with no street address, and 20 staff located in Denver or Boulder on LinkedIn
- AI stack
- FruGPT (in-house), GPT-4o, Claude
Some of the most ambitious AI builds on this list, and most of that work is not marketing. For the University of Wyoming it built an IEP platform with 6 specialized AI agents that cut IEP creation time 70%. FruGPT, its enterprise AI platform, reports a 90% cut in RFP response time across 90,000+ documents, and its PDF accessibility remediation writes alt text with GPT-4o and falls back to Claude.
It keeps a digital marketing line covering SEO, paid media, content marketing and email, with a Denver-based Director of AI Strategy and SEO, Patrick Scott, but that page describes no AI workflow. The site states a Denver office with no street address, and 20 staff are located in Denver or Boulder on LinkedIn, including founder Brad Anderson.
The pick when the job is an AI build as much as a marketing program.
9. Planet Media
9Planet Media
Kurt Whitt, Chief Executive Officer, Planet Media
- Best for
- Sustainability brands with hands-on automation
- Location
- Neusteters Building, 720 16th St, Suite 501, downtown Denver, with 2 staff located in Denver on LinkedIn
- AI stack
- n8n, Make, Zapier, Claude, ChatGPT
A small downtown studio that builds the automation itself, for sustainability brands only. It builds n8n and Make workflows connecting Gmail, Sheets, a CRM, Slack and Notion, drafts content with Claude and ChatGPT that people then refine, and shipped a Shopify checkout carbon-impact calculator for a B Corp client in 5 days. For Green On Board it built the AI assistant on every page, trained on a knowledge base Planet Media wrote, and loaded and reviewed 2,420 businesses into the directory.
No outcome number is tied to its AI work, and LinkedIn shows 2 staff in Denver, CEO Kurt Whitt and a business development lead. I know the arithmetic from my own company: "Nitrosend leverages AI-assisted development, enabling a 3-person team to ship like a team of 20." It works from the Neusteters Building at 720 16th St, Suite 501.
The pick for sustainability brands that want automation built, not described.
10. Peaks Digital Marketing
10Peaks Digital Marketing
David Finberg, Chief Executive Officer, Peaks Digital Marketing
- Best for
- SEO and lead generation with an AI engineer
- Location
- Prints a Denver address on West 12th Avenue, with 10 staff located in Denver on LinkedIn
- AI stack
- ChatGPT, Google Gemini
A Denver SEO and lead-generation shop with an engineer for the automation. Its team page lists a Full Stack Developer and AI Automation Engineer, and it uses ChatGPT and Google Gemini to find content optimizations and scale programmatic SEO. No case result is tied to that AI use. The case numbers are search and lead results: for Polaris, closes rose 800% and call volume 366%, from 10-15 leads a month to 50-70, Residential Systems Inc grew 20% and generated $6 million in revenue, and Modus Law's inbound inquiries rose 4x.
It prints a Denver address on West 12th Avenue, and has 10 staff located in Denver on LinkedIn, including CEO David Finberg.
The pick for local and B2B lead generation from search.
11. Lingows
11Lingows
Emily Moore, Chief Executive Officer, Lingows
- Best for
- Small-business AI automation with SEO
- Location
- 400 E Simpson St, Lafayette, in Boulder County, with 5 staff located in Denver or Boulder on LinkedIn
- AI stack
- Agentic workflows with human checkpoints, AI phone answering
The thinnest proof on the list, with a real AI practice and real people behind it. Lingows builds agentic workflows with human checkpoints and escalation, and sells automation workflows, autonomous agents, custom bots and AI phone answering as service lines. LinkedIn shows 5 staff located in Denver or Boulder, among them an Artificial Intelligence Project Manager, Jordan Strande, and the office is at 400 E Simpson St in Lafayette, in Boulder County.
Here is what is missing. It has no named client case studies: every case study is anonymized or about its own products, and one describes Lingows as a two-person operation. Its homepage shows a wall of big-brand client logos with no published case behind any of them. Hire it for a small AI build, not on reputation.
Ranked for a real AI practice and staff in the metro, with the thinnest proof on the list.
Also worth knowing
These Denver firms were considered and are not ranked.
Several have real AI and no Denver team. Firestarter has a Head of AI and Innovation building internal SEO workflows, with only its owner located in Denver on LinkedIn. Arcalea and Straight North are Chicago firms with no Denver staff. KickStart runs an AI voice bot for missed dental calls, with one Denver member. Digital Commerce Partners, GOSH, Brandify, Elevato, SkyDiamond, Digital Silk, Legal Guardian and ForeFront have no Denver staff. INSIDEA prints a Dover, Delaware registered-agent address. WebFX is based in Harrisburg, Pennsylvania, with 2 Denver members. Geeks360 is based in Hallandale Beach, Florida, with no staff here. Thrive has one member and a serviced suite at 1400 16th St, Suite 400.
Several sell AI visibility, which is not AI in delivery. Juris Digital sells GEO and ChatGPT ads. PufCreativ pairs a GEO line with email and SMS flows. Versa, Webolutions, Epidemic, Intergrowth and Artifact sell GEO or AI-search results. CSP Agency uses AI workflows for prompt mapping in a GEO program. Volume Nine has GEO, an AI-assisted drafting policy and 3 Denver staff, and prints 1312 17th St #942, a mailbox-style unit. SpearPoint has AEO copy and one Denver member.
Others run automation that is not AI, or describe AI with nothing behind it. Hybrid and RefractROI run email, loyalty and CRM flows. Hibu is a national small-business platform from Cedar Rapids, Iowa, whose Denver staff are sales reps. Metric Theory shows automated bidding and a custom regression script, and was acquired by Media.Monks. AdCellerant sells an AI media planner to media-company resellers. Colorado Digital has an AI transformation line and an AI lead role and no described workflow or result. Berry Interesting sells Zapier and chatbot integrations from a mailbox-style unit. Brand Iron has 3 Denver staff, and its only AI-in-delivery evidence is a homepage testimonial saying AI automation saved a client 20+ hours a week, with no workflow described; its 2590 Welton St, Suite 200 address is a bookable virtual-office suite. FOMO lists an "AI interviewer" and an "AI website" in a feature table, publishes no case numbers and states no Denver location. Adept Agency names no clients and prints a YourOffice virtual office.
CoreUpTech, Expert Design Hub, Team Crew Marketing, The Algorithm and Your Web Studios have no named clients and no case studies.
Software, IT, consulting, staffing and other firms that surface in Denver marketing searches are not marketing agencies and are not assessed here.
How to choose between them
For measurement and AI built on your own data, take Adswerve. Apartment owners and property managers have Digible, and franchise and multi-location brands have Location3. An enterprise that wants AI product builds and commerce alongside marketing should look at DEPT, and a consumer brand buying full-funnel media at scale at Wpromote.
B2B companies that want analytics done carefully have Two Octobers. Booyah Advertising is the established paid media team, and Fruition is for an AI build as much as a campaign. Sustainability brands have Planet Media, local and B2B service firms that live on search leads have Peaks Digital Marketing, and a small Front Range business that wants one AI workflow built has Lingows.

FAQ
Adswerve, for most brands that want measurement, media and AI built on their own first-party data, because it publishes named client builds with numbers. Digible is second and does a narrower job: marketing for apartment communities, with its own call, compliance and posting tools. After that the list splits by need, with Location3 for franchises and DEPT for enterprise AI builds.
The difference shows in what each one publishes. Adswerve shows a generative AI sentiment pipeline it built for Six Flags. Digible shows its call-labeling tool and the lease-opportunity rate it reports. Location3 shows what machine-learning bidding did for Mathnasium's lead volume. Read those three pages and you will know which one describes your problem.
Between $600 and $15,000 a month on retainer, before ad spend. Entry SEO plans start at $600 a month, paid media management at $995 to $4,000, and most multi-channel retainers from Denver firms run $4,000 to $9,500 or more. Bigger programs reach $15,000 a month.
Blennd publishes its ranges: $2,500 to $4,000 a month for focused SEO and AI-visibility work, $1,800 to $4,000 for paid media management with ad spend excluded, and $4,000 to $9,500+ for most multi-channel growth retainers. Creative Options Marketing's typical retainers run $3,000 to $15,000 a month, with projects from $5,000. Volume Nine puts the average starting point for a full-service contract at about $5,000 a month. At the low end, SpearPoint's SEO plans for startups start at $600 a month and Codesynap's flat ad management fee starts at $995 a month. Of the eleven ranked, Two Octobers' paid media fees start at $1,000 a month, on media spends of $3,000 to $100,000.
Colorado job postings carry pay ranges, which makes a hire easy to price. MERGE pays a Denver senior account director $120,700 to $147,550, Mission One Media pays a paid search specialist $50,000 to $60,000, and Volume Nine pays a digital marketing strategist $55,000 to $70,000. A mid-range retainer costs about what one mid-level marketer does, and buys a team.
Look for one of four things: a named tool with a described function, a named workflow, a person with an AI or automation role on the team, or a case study that ties automation to a number. A banner is not evidence.
Every AI point on this page links to one of those. Adswerve names the client and the result for Betterment's bidding script. Two Octobers describes how Treeline keeps calculations in code while AI drafts the analysis.
On four criteria: AI automation out of 20, and specialization, published evidence and a real Denver team, each out of 10, for a total out of 50. Each card links the sources behind its score.
