Every marketing agency says it uses AI now. It’s on the homepage, in the pitch deck, sometimes in the first line of the cold email. Fine. But where, exactly, does the AI sit in the work? Is it writing the blog? Watching what ChatGPT says about you? Picking accounts? Living inside your CRM?

Those are wildly different things to pay for. And if you sell to other businesses and a deal takes six months, you really only care about one of them: does it end in a conversation your sales team can work? So that’s the lens here. Where does each agency put its AI, and how close is that to money?
How did I pick these seven?
I went looking for B2B agencies that actually explain, on their own site, what the AI does in their delivery. A vague “AI-powered” badge didn’t count. Then I asked three things of each one. Can you measure what the AI touches? Is the proof named, real clients with real numbers? And is it obvious who they’re for?
Everything here comes from each agency’s own site as it read in late October 2026. If I couldn’t confirm something, it’s not in.
Full disclosure before we start. Content RevOps is mine. It’s also number one here. Make of that what you will.
How do they compare at a glance?

1. Content RevOps
Who it suits: B2B companies with long sales cycles, where the content person, the CRM person, and sales have never really been in one room.
I started the company in 2024 because I kept walking into the same mess. Years of guides and webinars and case studies, and then the CFO asks “so what did all that bring in?” and there’s silence. The blog’s in one tool. The CRM’s in another. The freelancer who writes the posts has never met whoever set up HubSpot.
So we’re a demand generation agency that does both bits. The writing buyers want before they’ll take a call, yes, but also the plumbing: CRM, CMS, tracking. That way, for once, you can point at a piece and say “that one started a deal”.
And the AI? For us it’s mostly a measuring stick. We take the questions your buyers actually ask, run them through several AI assistants by API, and do it three times each. Why three? Ask the same thing twice and you’ll often get two different answers. So a single ChatGPT screenshot means very little. After three runs you know if you show up always, now and then, or not at all, and who shows up in your place.
A few client results:
- Westlab got to 241 inbound leads and an 869% return in three months.
- Behavior Advantage brought cost per lead down from about $500 to $10.
- Radius cut cost per lead from $150 to about $45 while halving ad spend.
- At Banking Crowded, about 22% of inbound traffic now comes from AI assistants, and those leads convert at about five times the usual rate.
Smaller companies can start with consulting from $2,000 a month, or the full system from $4,200.
Worth knowing: we’re young. Founded 2024, so not many reviews yet (5.0 on Google from five, 5.0 on Clutch from one). And we only do B2B with a considered sale. Selling to consumers? Go look at NoGood or Single Grain.
2. NoGood
Who it suits: SaaS, fintech, health, and AI companies with money to spend, who’d like one team doing paid, organic, and creative together.
NoGood calls itself AI-native, and to their credit they say what that means. They’ve built their own systems and agents, running next to tools from partners like Claude and Google. Every client gets an exec dashboard and an AI agent you can just ask about your own numbers. On the AI search side they’ve partnered with Goodie AI, a platform that tracks how brands show up in ChatGPT, Gemini, and Perplexity.
The bit I actually liked? They hold back. AI does the research, data crunching, and reporting, but they keep it out of most of the creative and strategy work on purpose. MongoDB and Intuit are on the site, and they report 84% client retention.
Worth knowing: it isn’t cheap. Their own site puts the average retainer above $20,000 a month. And B2B is one lane among several; they do a lot of consumer and eCommerce too.
3. Single Grain
Who it suits: marketing teams who want the AI automation installed in their own tools, and then want to run it themselves.
Single Grain is very hands-on about this. They’ll put AI agents, automated workflows, and predictive tools into your martech stack (and your Slack), train your people on them, and keep them running. Alongside that you get answer engine optimisation, which is basically getting cited in AI answers, plus SEO, paid, and content.
The case study that caught my eye was SmartRent getting 10 sales-qualified leads a month from AI assistants. They also say they’ve served 500+ companies with a 3.2x average client return, and there are testimonials from marketing leaders at Nextiva and Lever.
Worth knowing: there’s a fair bit of consumer work in the client list, so ask for examples near your market. And an agent living in your Slack needs somebody on your side to own it after launch. No prices on the site.
4. Directive
Who it suits: B2B tech, industrial, and services brands that spend real money on paid media and want the budget calls backed by data.
Directive’s one of the big ones. Their homepage says 130+ strategists and $1B+ in revenue generated, with Calendly, BlackLine, Gong, and SentinelOne on the client wall. Their AI is a platform they built called Stratos. You feed it CRM, paid, SEO, finance, and ops data, and it ranks the accounts that look most like the customers you already love.
It also does marketing mix modelling. In plain English, that’s an estimate of how much pipeline each channel is really driving, so next quarter’s money goes where it’s working.
Worth knowing: I couldn’t find anything about AI search on the Stratos page. If your worry is ChatGPT recommending a competitor, ask them about it directly. And at their size, it’s fair to ask who’ll actually be on your account week to week. No published pricing.
5. Omniscient Digital
Who it suits: B2B software companies that want to be the name AI assistants recommend, and are happy to play the long organic game.
Omniscient’s pitch is getting B2B brands recommended in AI and search, then turning that into pipeline. They track AI share of voice and citation share, so how often you’re mentioned and cited next to competitors. Their case studies don’t mess around. Convert grew LLM visibility 81% and AI citations 140% in 60 days. OnBoard became the number one most visible brand in AI search, with AI visibility up 88%. Teambridge got $400,000 of qualified pipeline from SEO.
SAP, Adobe, Asana, and Retool are among their clients.
Worth knowing: organic only, meaning SEO, AEO, content, and digital PR. You’ll want someone else for paid. And they’re upfront that full-service starts at $120,000 a year.
6. Growth Plays
Who it suits: B2B SaaS, dev tools, and (a bit unusually) investment funds, if what they want is content they can tie to pipeline.
Growth Plays builds what they call content engines. The writing comes out of AI workflows with a human checking it, fed from a knowledge base of your positioning so it doesn’t drift off message. They track how visible you are in generative AI too.
My favourite detail: they’ve built their own tool to check how AI models describe you when they do mention you. Smart, because getting named in a bad light isn’t a win. Attribution runs through HubSpot, Bizible, and Roadway AI, and Lattice, Calendly, LangChain, Vercel, and LaunchDarkly are on the client list.
Worth knowing: they’re a content shop first. No paid media, and no prices on the site.
7. Gripped
Who it suits: UK and European SaaS, AI, and tech firms somewhere between £2M and £50M in annual recurring revenue.
London, 2017, roughly 25 people, 160-plus SaaS, AI, and tech clients so far. Gripped plans demand gen for the whole buying group rather than one lucky contact. Where’s the AI? It’s one channel among several, called generative engine optimisation. In practice that means reworking your content and site until ChatGPT, Google’s AI Overviews, Perplexity, and Claude start picking you up. Think structured data, entity building (making it obvious to the models who you are), and formats machines read easily.
Their pipeline proof comes from paid search and social, to be fair: £1.3m of new pipeline in a quarter for Crownpeak, and a 108% year-on-year jump in sales opportunities for Terryberry.
Worth knowing: SaaS and tech only. Retainers run £5K to £15K a month on rolling contracts with three months’ notice, and media spend is on top.
So which one fits you?
My honest advice? Find the leak first. Whichever agency’s AI sits closest to it is probably your pick.
Paid is your engine and you want sharper targeting and budget calls? Directive or Single Grain. Want a big AI-native team on every channel, and you’ve got the budget? NoGood. Worried AI assistants keep recommending your competitors instead of you? Omniscient Digital, Growth Plays, and Gripped each come at that from a different direction.
And if it’s the old story, years of content you can’t tie to a single deal because content, CRM, and sales all run separately, well, that’s the exact gap I built Content RevOps for.
Whoever you end up talking to, ask them early: what will I be able to measure in 90 days that I can’t measure today? You’ll learn a lot about where their AI really sits.
