Much of the AI on Baltimore agency sites is AI search visibility, or AI on a service line with no client work behind it. "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.
1. Jellyfish
1Jellyfish
Jai Amin, Chief Solutions Officer, Media Activation, Jellyfish
- Best for
- Large brands wanting AI content and predictive bidding
- Location
- Baltimore office listed on its contact page, no street address printed; 27 staff located in Baltimore on LinkedIn
- AI stack
- Pencil, Share of Model, Jellyfish Social Agents (Google Gemini)
Jellyfish is a global digital agency, and its AI practice names three products: Pencil for ad creative, Share of Model for tracking how language models see a brand, and Social Agents built on Google Gemini. Its best AI results are global work, not Baltimore work. For M&S it delivered over 20k product descriptions with generative AI in 7 months of live production, reporting 80% faster content delivery and 30% lower unit costs. For Vodafone Italy a predictive lifetime-value model fed to Google Ads bidding lifted activations 79% and ROAS 17%. Its homepage line that Pencil makes assets 55% faster has no case behind it.
Its contact page lists a Baltimore office but prints no street address. 27 staff are located in Baltimore on LinkedIn, including Chief Solutions Officer Jai Amin.
The pick for a large brand that wants AI content production and predictive bidding with a Baltimore bench, knowing the published AI work was done elsewhere.
2. Merkle
2Merkle
Spencer Schmidt, Account Director, Merkle
- Best for
- Enterprise brands wanting data-led CX with generative AI
- Location
- Columbia, MD office at 7001 Columbia Gateway Drive; 8 staff located in Baltimore and 25 in Columbia on LinkedIn
- Platforms
- Treasure AI
Merkle is a customer-data and experience firm inside dentsu, and its generative-AI proof is one case. It turned a major comparison platform's chatbot into a proactive savings tool with generative AI, dynamic content and AI-driven pricing, reporting a 25% uplift in CRM-driven conversions. That case names no client, and the rest of the page is mostly leadership bios. Treasure AI is listed among its technology partnerships.
Its bigger numbers are site work, not AI: a Volvo Trucks rebuild after which 720% more people found a local dealership. Its Maryland office is at 7001 Columbia Gateway Drive in Columbia, in the metro rather than the city. 33 staff are on LinkedIn nearby, 8 located in Baltimore and 25 in Columbia, including Account Director Spencer Schmidt.
The pick for an enterprise brand that wants data and CX work with generative AI from a large Maryland team, with the one AI case taken on trust.
3. Mindgrub
3Mindgrub
Robbie Callen, Vice President, Innovation, Mindgrub
- Best for
- Organizations wanting custom AI chatbots plus marketing
- Location
- 1215 East Fort Avenue, Suite 200, Baltimore; 26 staff located in Baltimore on LinkedIn
- AI stack
- Fine-tuned LLM chatbot (Coppin State), AI Career Coach (SciPhD Flamingo)
Mindgrub is a Baltimore technology agency whose AI work is builds for clients. For Coppin State University it fine-tuned a large language model into Jackson, a student-support chatbot that answers only from Coppin's vetted content. For SciPhD it built an on-demand AI Career Coach into the Flamingo platform, analyzing job descriptions and skills gaps. Neither case publishes a business result, and it also sells custom AI agents for sales and support systems.
It is a marketing agency as well as a builder: its digital marketing practice runs campaigns from SEO to paid social, display and email, and Visit Baltimore is among its clients. Its office is at 1215 East Fort Avenue, Suite 200, and 26 staff are located in Baltimore on LinkedIn, including Vice President of Innovation Robbie Callen.
The pick for an organization that wants a Baltimore team to build an AI chatbot or agent and run the marketing around it.
Also worth knowing
These Baltimore firms were considered and are not ranked.
Imre, in Towson with 11 staff in Baltimore on LinkedIn, runs the Imre Data Management System, a campaign-data pipeline on Fivetran and Databricks that cut its own reporting from 10 to 20 hours to under one hour. The only thing calling it AI is PM360's award category, and no model appears in its client work. Groove Commerce, with 7 Baltimore staff, reports a 46% flow-revenue lift from rule-based email automation, which is not AI.
Several have a real Baltimore team and no AI in delivery. TBC has 43 staff in Baltimore on LinkedIn and describes "George", its AI-enabled marketing stack, only in general terms, with no named tool, client workflow or result. AltaVista has 42 staff and sells "Alta Intelligence" AI service lines with no named tool, client or case. MOJO, in Pasadena, MD, offers an AI strategy and integration service with no client case. Planit, Warschawski, MGH, Mission and Crosby Marketing describe no AI in their client work.
Others have AI claims and no Baltimore team. What Works Studio built an AI prospecting engine for Greenwell, with no number and no Baltimore staff. Maryland Web Design sells AI automation systems with no client case. Thrive is a Texas firm whose AI results are AI-search citations. INSIDEA and Intero Digital state no Baltimore office or team, and INSIDEA, Belkins and Zonic Media print a Dover, Delaware registered-agent address.
Several sell AI search visibility, not AI in the work. Klik Digital, Dragonfly, Agency 102, PosiRank, The Cyphers Agency, MarketKeep, MNM Digital Agency, Gigawatt, Exponential Media, Best Fit Digital and BizMarquee sell AI-search visibility or AI service lines with no client workflow. Black Propeller, in Abingdon, mentions Pixis AI and "a global team of AI engineers" in one line. Bimeo Digital, Crownsville Media and Pink Dog Digital state that they write without AI.
Clarity Consulting Group, CrunchGrowth and GEO Search and Social have no named clients or case studies.
Software, IT, consulting, staffing and other firms that surface in Baltimore marketing searches are not marketing agencies and are not assessed here.
How to choose between them
A large brand with a heavy content or media program should start with Jellyfish, the only firm here with named AI products and published AI results with numbers, and should ask which of that work its Baltimore team would run. An enterprise brand that wants customer data, loyalty and experience work with generative AI inside it has Merkle, from Columbia rather than the city. A university, nonprofit or platform that wants a custom AI chatbot built and the marketing run around it has Mindgrub, the only one of the three with a Baltimore street address on its own site.
My view is that the next step is setting a goal and letting an agent build the program, writing and sending for each contact one at a time. So ask each of these firms which steps its agents run and which its people run.

I score every marketing agency here on four criteria, for a total out of 50: AI automation out of 20, and specialization, published evidence and a real Baltimore team, each out of 10. Each card links the sources behind its score.
Nitrosend, which I co-founded, publishes this page. It is an email platform for agencies, not a marketing agency, and is not ranked.
FAQ
Jellyfish, because it names its AI tools and publishes what they did: over 20k M&S product descriptions produced with generative AI in 7 months. That work was done by its global teams, not in Baltimore, and its Baltimore office has no printed street address. Merkle is second, with one generative-AI case, and Mindgrub is third, the most local of the three.
What each one publishes shows the difference. Jellyfish documents its Vodafone Italy bidding model. Merkle describes its chatbot case on its AI page. Mindgrub shows the Coppin State chatbot it built. Read those pages and you will know which one describes your business.
Between $1,000 and $5,000 a month for most local marketing programs, $350 to $6,000 or more a month for SEO, and $1,000 to $17K for a website build, before ad spend. None of the three ranked firms prints a price, so these figures come from Baltimore-area firms that publish them.
Urban Ignite, on Saint Paul Street, sells packages from $1,000, $3,000 and $5,000 a month. MarketKeep in Towson says its SEO clients run from $350 to $6,000 or more a month. Further Insights in Hampden prices SEO at $750 or $1,500 a month and social media at $1,250 or $2,500 a month. MNM Digital Agency in Hanover starts Google Ads management around $500 a month and puts social media plans at $500 to $2,000+ a month. PMDS builds WordPress sites from $1,000 and Webflow sites from $1,500, and Crownsville Media's 2025 website builds ran from $3,500 to $17K. At the top, Black Propeller in Abingdon works with brands investing at least $10k a month in paid media.
Job postings show what the people cost. A Jellyfish Account Director earns $150K to $175K and a Senior Paid Social Manager $80K to $100K, in postings that list Baltimore with other cities. A Mindgrub Account Director earns $130,000 to $140,000, and at Planit a Director of Social Media earns $95k to $125k and a Social Media Manager $55k to $70k.
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. In Baltimore much of what is sold as AI is AI search visibility, which gets a firm cited by ChatGPT but does not automate any work.
Every AI point on this page links to one of those. Jellyfish ties generative AI to M&S content volume and cost. Mindgrub shows the Coppin State chatbot it built.
