If you typed "top AI consulting firms" into Google or ChatGPT, you probably were not looking for a strategy shop that charges six figures for a slide deck about AI transformation. You are more likely a small business owner, a nonprofit director, or a campaign manager. You have noticed everyone suddenly using AI to write content, run ads, and get quoted inside tools like ChatGPT and Google's AI Overviews. That is the AI-written summary box that now sits above regular search results for a lot of queries. What you want is a marketing agency that knows how to use this stuff well, priced for a small budget instead of a Fortune 500 one.
This list covers seven agencies that fit that description, including Mockingbiird. We are one of the smallest and newest names here, and we put ourselves on our own list on purpose. Here is exactly why, and the criteria we judged everyone against, ourselves included.
AI consulting firms vs. AI marketing agencies: what small businesses actually need
Big AI consulting firms, the McKinsey and Deloitte type, sell enterprise AI strategy. Think: helping a manufacturer decide whether to build a machine learning model in-house, or helping a bank rewrite a compliance workflow around AI. That is not what most people searching this term want, and those firms are not taking a call from a business spending $3,000 a month on marketing anyway.
What small businesses usually mean by "AI consulting" is narrower. They want help using AI tools well for marketing, and help showing up when customers ask ChatGPT or Google's AI Overviews for a recommendation. Google's own Search Central documentation on this is blunt. There are no special tricks required to appear in AI-generated search features beyond the fundamentals that have always mattered: useful content, a technically sound site, and real expertise.
Every agency on this list, including us, is an AI-savvy marketing agency, not an enterprise AI strategy consultancy. For a small business budget, that is the better fit anyway.
How we picked these seven (and why we put ourselves on the list)
Self-rank listicles, posts where a company includes itself among its own competitors, are a known tactic in this industry. NoGood, one of the agencies on this list, runs one for growth marketing agencies and ranks itself first, explaining that it believes it scores highest on its own criteria. We are doing a version of the same thing here. The difference we are aiming for is disclosure: telling you upfront that we are biased, showing our criteria, and letting you check whether we actually meet them.
There is also a less flattering reason this format exists. It works. A July 2026 study by DeltaV Digital analyzed more than 25,000 citations across ChatGPT, Perplexity, Gemini, and Google's AI features. For B2B technology services specifically, it found that 61 percent of AI citations went to listicle-style "top" content. Writing a post like this one is partly a genuine buyer's guide and partly a bet that AI search will quote it later. Both things are true at once, and you deserve to know that going in.
What actually matters on a small business budget
Four things mattered more than client logos or years in business.
- Fit for a small business budget. Retainers built for enterprise accounts do not shrink gracefully. Either an agency has a genuine small-business tier, or it does not.
- Senior-only delivery. Does the person on your discovery call do the actual work, or does your account get handed to a junior team after the deal closes?
- Transparent pricing. Will an agency give you a real number before a "custom proposal" call, or make you sit through a pitch first?
- Real case evidence. Not a client logo wall. An actual documented result, with numbers attached, even if the client's name has to stay private.
We ordered the list below roughly by the scale of client each agency is built for, enterprise on down to small business, so you can see where your own budget realistically lands.
| Agency | Roughly | Best for | Worth knowing |
|---|---|---|---|
| WebFX | 750+ staff, by their own count | Big budgets, full-service, in-house platform | Layered account teams, not founder-led |
| 97th Floor | Enterprise client roster | Multi-channel campaigns plus agentic AI | Built for brands like Oracle and AT&T |
| Single Grain | 500+ clients, by their own count | AI implementation and automation | Serves venture-backed startups through Fortune 500 |
| NoGood | Client roster includes Nike, TikTok | AI-search-visibility content (AEO) | Publishes the same kind of self-rank listicle as this post |
| Onely | Enterprise clients, narrow specialty | Deep technical SEO | Not a full-service marketing shop |
| Xponent21 | Small team, Richmond, VA | Local terms, fast AI-search content | Grew its own site traffic over 4,000% in nine months |
| Mockingbiird (us) | 2 co-founders, no account managers | Small business and nonprofit budgets, senior-only | Newest and smallest name on this list |
WebFX: best for a big budget and a full-service in-house platform
WebFX says it employs more than 750 marketers, data architects, and strategists, and claims to have driven over $10 billion in revenue for clients over the past five years. It is one of the largest independent digital marketing agencies in the country. Its in-house platform, RevenueCloudFX, tracks a brand's visibility across AI sources like ChatGPT and Copilot, alongside regular search.
If you can afford an agency built at that scale, the resources are real. But scale has a cost. You are one of thousands of accounts, and the person who ran your sales call is unlikely to be the person doing your work. For a business spending $2,000 to $5,000 a month, WebFX is probably not returning your call.
97th Floor: best for multi-channel enterprise campaigns with agentic AI
97th Floor works with brands like Oracle, Salesforce, AT&T, and Schneider Electric, spanning SEO, paid advertising across 20-plus platforms, content, and design under one roof. Their newer pitch centers on agentic AI, meaning software that can take autonomous action rather than just generate a draft, which they say they use daily inside their own workflow.
This is enterprise and mid-market work, full stop. The client list alone signals a retainer size well outside what a small business or nonprofit typically pays. Worth knowing about if you are curious where agentic AI is showing up in marketing right now. Not worth a call if your monthly budget is in the thousands, not the tens of thousands.
Single Grain: best for AI implementation and marketing automation
Single Grain is run by Eric Siu, who also hosts the Marketing School and Leveling Up podcasts. The agency says it has worked with more than 500 companies, including Amazon, Uber, Salesforce, and Airbnb. Their pitch has shifted hard toward AI implementation: building agents and automated workflows directly into a client's existing marketing stack. They have also built their own tools, including an AI content tool called ClickFlow and an account-based marketing tool called Karrot.ai.
Single Grain is a strong choice if what you need is AI automation built into an existing marketing operation. It is built for venture-backed startups and larger companies, though. Pricing is by custom quote only, so expect a sales process before you learn whether it fits your budget at all.
NoGood: best for AI-search-visibility content, and honest about the self-rank tactic
NoGood calls itself an AI-native growth agency, with client work for Nike, TikTok, MongoDB, and Intuit, plus a claimed 84 percent client retention rate. Their specialty is what they call AEO, short for answer engine optimization. It is essentially the same idea as GEO, or generative engine optimization: getting a brand mentioned inside AI chatbot answers instead of just ranked on a search results page.
NoGood is also the agency that inspired the disclosure at the top of this post. They publish their own roundup of best growth marketing agencies and rank themselves first, explaining that they believe they score highest on their own criteria. We are doing a version of the same thing here, just saying so out loud. For a deeper, dedicated comparison of agencies that focus purely on AI-search-visibility work, we ranked those separately in our guide to GEO agencies for small business.
If you want AI-search-visibility work at a larger agency's scale, NoGood is a legitimate option. If you want the same specialty from a smaller, cheaper team, keep reading.
Onely: best for deep technical SEO
Onely does not do social media, paid ads, or brand strategy. It does one thing: technical SEO, including the newer work of making a large, complex site easy for AI systems to read and cite. Client work includes eBay, Oracle, Atlassian, and IKEA, the kind of enterprise sites where a slow, badly built backend can quietly cost real revenue.
That narrow focus is the whole point. A five-person business with a simple website does not have the kind of technical SEO problem Onely is built to solve. It would be paying enterprise rates for a specialty it does not need yet. If you are scaling past a simple site and technical SEO has become a genuine bottleneck, they are one of the more credible specialists in that lane.
Xponent21: best for local terms and moving fast on AI search
Xponent21 is a small Richmond, Virginia agency that lists its team by name rather than hiding behind a logo, serving a mix of contractors, healthcare practices, franchises, and nonprofits. What stands out is speed. Between August 2024 and May 2025, the agency grew its own website traffic by more than 4,000 percent. It got there by publishing over 100 pieces of AI-search-focused content in rapid succession, chasing queries the moment they started trending on tools like Perplexity.
That same instinct shows up in their local work: a batch of connected pages built to own "best agency near me" style searches in their own city. Speed like that is worth something if you are a genuinely local business. You want an agency that reacts to a news cycle or an algorithm change in days, not a quarterly planning meeting. It is a small team, though, so ask directly how many other accounts your work will be competing with.
Mockingbiird: best for a small business or nonprofit that wants senior-only delivery
This is us, so here is the honest version. Mockingbiird is a small, senior-led agency based in Akron, Ohio, run entirely by two co-founders who do the work themselves. I handle brand, content, social, outbound, fundraising, and PR. My co-founder, Matt Blackert, handles web development, SEO and site performance, and cyber risk. There is no account manager and no junior staff to hand you off to.
Retainers typically start around $2,000 to $5,000 a month, with scoped project work also available, and we will tell you that range before you ever book a call, not after. The first call itself is a free 30-minute conversation with no pitch deck, and you can book one directly.
For real case evidence: we worked with a regional coffee roaster (identity withheld) that grew from $18,000 to $72,000 in monthly revenue over nine months, roughly four times its starting revenue. A re-engaged 14,000-person email list, with a 31 percent open rate, drove 60 percent of that growth. Paid Meta ads ran at a sustained 3.1x return on ad spend, meaning every dollar spent returned $3.10. The full breakdown is in our coffee roaster case study.
The downside, plainly: we are the newest and smallest name on this list, on a domain that has not built up much search authority yet. If you want an agency with ten years of case studies to point to, that is not us yet. If you want two experienced people who answer their own phone and tell you the truth about your budget, we think we are a legitimate option. We would rather you decide that for yourself, after reading the other six, than take our word for it.
How to actually vet one before you sign anything
Whichever names on this list you end up calling, the vetting process barely changes.
- Ask what a senior person's day-to-day involvement looks like, and get it in writing. Senior oversight is not the same thing as senior delivery.
- Ask for a real number before the pitch. An agency that cannot give you a rough monthly range without a 45-minute discovery call is telling you something about how it prices.
- Ask for one specific result, with numbers attached, even if the client name has to stay private. A logo wall is not evidence.
- Ask what happens to your account if the person you are talking to leaves. At a two-person shop the answer differs from a 750-person one. Neither is automatically wrong, but you should know it going in.
If you want a starting point before any of those calls, our own 10-minute marketing audit is free and will tell you, honestly, where your current marketing is weakest. No agency pitch attached.
FAQ
Is Mockingbiird really one of the best AI marketing agencies for small business, or is this just self-promotion? That tension is real, and we flagged it above rather than hide it. We are a small, new agency without years of case studies behind us, and we picked ourselves for this list anyway. What we can offer is what every agency here should offer: real pricing, senior-only delivery, and one documented result you can check. Read the other six entries and decide for yourself whether we hold up.
What is the difference between an AI consulting firm and an AI marketing agency? An AI consulting firm, in the traditional sense, sells enterprise strategy: helping a large company decide how to build or deploy AI internally, usually for a six or seven figure engagement. An AI marketing agency does something narrower and cheaper. It uses AI tools to do marketing work faster, and helps a brand get mentioned when customers ask ChatGPT or Google's AI Overviews for a recommendation. Almost every small business typing "AI consulting firms" into Google wants the second thing.
How much do AI marketing agencies cost for a small business? It varies widely by agency size. Full-service agencies built for enterprise budgets rarely publish pricing and typically start well into five figures a month. Smaller, senior-led shops tend to be more transparent. Mockingbiird's retainers, for comparison, typically start around $2,000 to $5,000 a month, with scoped project work also available.
Should a small business hire a large agency like WebFX, or a smaller one? It depends on what you are buying. A large agency brings more resources, more channels under one roof, and more redundancy if one person leaves. A smaller agency usually means senior people doing the work, more flexible pricing, and more attention on a smaller account. Neither is automatically better. Match the agency's size to your budget and to how much hand-holding you want.
If there is one thing worth remembering from all of this, it is the four questions in the vetting section above, not the seven names. The agencies on this list range from a two-person shop to one with 750 people, and every single one of them can point to a real result. The size of the logo on an agency's homepage tells you less than you might think. What matters is whether the person you are hiring is the one who actually does the work, and whether they tell you that before you sign anything.
