The senior operator for AI agents in B2B growth marketing.
Most B2B marketing teams are buying AI tools. The ones pulling ahead are operating AI agents: designing the system, deploying it across paid media, SEO and demand generation, and governing what it actually does. This is the seat that runs that system.
What it is.
The AI Agent Operator is a senior human role. The agents do the work; the operator runs the system. It sits inside Marketing Ops, alongside the function that already manages people and tools, and takes accountability for the agent stack the way Marketing Ops takes accountability for the rest of the operating model.
The role is new in name. The work is not. For eighteen years I’ve been designing growth systems for B2B companies expanding internationally: SEO platforms, paid-media stacks, attribution rebuilds, content engines. Agents are the next layer of that system, and they need someone with the same shape of accountability who is also fluent in how agents fail.
A senior practitioner who designs, deploys and governs the AI agent system that runs B2B marketing execution.
Distinct from an agency, which provides a team for retainer-based execution. Distinct from a tool vendor, which sells you software. Distinct from an IT or DevOps “AI Ops” role, which owns infrastructure rather than marketing outcomes. The operator is accountable for the system’s outputs, the way a Head of Marketing is accountable for the team’s.
Why now.
The shape of B2B marketing operations has changed faster in the last twelve months than in the previous ten years. Three things are happening at once, and the senior leaders feeling them most acutely tend to be in B2B SaaS, cybersecurity, fintech and legal-tech.
Tools are becoming workers.
The 2025 MarTech landscape now includes more than 15,000 solutions. The interesting ones aren’t tools anymore. They’re agents that operate on a brief and report back. The job of selecting and managing them is no longer a stack decision; it’s an operating-model decision.
Marketing ops is becoming agent ops.
“B2B marketing operations roles will evolve from managing tools to designing agent workflows.” That quote is from Demand Gen Report’s 2025 review. The skill that matters is no longer prompt engineering. It’s architecting systems where multiple specialised agents coordinate without burning budget.
Senior marketers want their time back.
The teams pulling ahead are using agents to absorb manual execution, so VPs and CMOs can move up the value chain. The cost of staying manual is no longer just inefficient. It’s a strategic mistake.
Agency and operator.
Most B2B companies still default to “find an agency,” and that’s the right call for most marketing work. I run one, so I’d know. The specific job of designing and running a system of AI agents inside the marketing function has a different shape. The operator role sits alongside the agency model, not in place of it.
Marketing agency
- A team works on your behalf, on retainer.
- Scale comes from adding people.
- The team operates inside its own workflow.
- Accountability is on the work delivered.
- Best for creative, campaigns, and brand.
AI agent operator
- You own the system; the operator runs it.
- Scale comes from improving the agents.
- The stack is in your account, fully documented.
- Accountability is on outputs and governance.
- Best for the always-on operating layer.
How I work.
The three engagement shapes below cover almost everything. Most engagements start with the first one (a short call, free for the right fit) and progress only if there’s a real problem worth solving.
Strategy call
- Honest read on where AI agents fit in your stack.
- Two or three workflows worth piloting first.
- Whether an operator engagement is a fit at all. Often it isn’t.
- No prep required from your side.
Operator audit
- Full audit of your current marketing stack and ops model.
- Map of agent workflows by ROI, complexity and risk.
- 90-day operator roadmap with clear ownership.
- Final readout with your leadership team.
Fractional operator
- Embedded operator role across paid media, SEO and demand gen.
- Owns the agent stack end-to-end.
- Reports into the CMO or Head of Marketing.
- Multilingual coverage where international growth requires it.

Questions.
What does an AI Agent Operator actually do day to day?
The operator owns the agent stack the way a Head of Marketing owns the team. That means designing the workflows agents run, choosing which tools and models they sit on top of, defining the briefs and guardrails, monitoring outputs, fixing failures, and coordinating with the human team on what stays human.
In a B2B growth context, the daily work covers paid media bid management, SEO and content production, competitive monitoring, lead routing, attribution and pipeline reporting. The operator does not write copy or run campaigns by hand. The agents do that, supervised.
Is this a fractional CMO role with a different name?
No. A fractional CMO owns marketing strategy, brand and the team. An AI Agent Operator owns the agent stack: the system that executes the work the team used to do manually. They sit next to each other; they don’t replace each other.
In smaller teams, one person might wear both hats. In Series B-and-above teams, they’re usually separate.
How big is the AI agents market in B2B marketing?
The global AI agents market is projected to grow from USD 7.84 billion in 2025 to USD 52.62 billion by 2030, a compound annual growth rate of 46.3 percent. The World Economic Forum projects 170 million new roles emerging by 2030, with the strongest growth in agent governance and orchestration. Forrester forecasts that 6.1 percent of US jobs will shift due to AI and automation by 2030, equivalent to 10.4 million roles.
Sources · MarketsandMarkets · World Economic Forum · ForresterWhat kind of company is the right fit for this engagement?
The most common fit is a venture-backed B2B SaaS company between Series B and growth stage, with a CMO or Head of Marketing in seat, an existing paid-media or SEO program in market, and a real reason to expand internationally, usually into a market the central team doesn’t operate in natively.
If the team is pre-product-market-fit, or the CMO is expecting a vendor relationship rather than an embedded operator, the engagement won’t work. The strategy call is the right place to figure that out, both ways.
Why does multilingual experience matter here?
Most B2B companies that engage an operator are expanding internationally. AI agents producing content, search ads or attribution in markets the central team does not speak break in subtle and expensive ways: wrong tone, wrong intent matching, wrong legal language, wrong implicit assumptions about the buyer.
An operator with native experience in English, Spanish and German across Europe and North America catches those mistakes earlier and ships campaigns that work in market, not only on paper. This is the part that’s hardest to outsource and the most expensive to get wrong.
Does this replace my agency?
It depends on what your agency does. If they are running paid media manually with a team of analysts on retainer, the answer is partly yes. The operator builds a system that does most of that work without retainer headcount. If they are a strategic creative or brand partner, no. Those jobs stay with humans.
In most engagements, the operator absorbs the execution layer and the agency relationship contracts to strategic work. We design that transition in the audit, not by surprise.
What's the relationship to COSEOM?
COSEOM is the agency I founded in 2008. It runs multilingual paid-media and SEO programs out of Barcelona, San Francisco, Stuttgart and Bangkok. The operator engagement is a separate, more senior offer: it’s me, working directly with the CMO, on the system rather than on individual campaigns.
Some engagements also use the COSEOM team for execution where it makes sense. Some don’t. The operator role is independent.
How fast can you start?
The 30-minute call is usually within a week. The audit is two weeks of work, scheduled four to six weeks out depending on the queue. Fractional engagements typically start within thirty days of the audit readout.
