Fractional Head of Marketing for B2B SaaS

Q: What is the difference between a fractional head of marketing and a fractional CMO?

Mostly title and altitude. A fractional CMO framing leans board-level, covering strategy, the team and the boardroom. The head-of-marketing framing leans hands-on: the same senior person, closer to execution, often the right fit for earlier-stage teams that want a builder-leader rather than an overseer. It is the same operator; the title matches how close to the work the client wants them.

01 / The problem

Earlier-stage teams need a builder who leads, not a leader who only directs.

At an earlier stage you do not need a board-level marketing figurehead with a team underneath to do the actual work — you need someone senior who sets the strategy and then builds and runs it. The gap is real: a junior marketer cannot own direction, and a full-time senior leader is a mid-six-figure cost with a layer of hires to be useful.

Strategy without hands

Advisors and part-time strategists hand you a plan and a deck, then leave the building to a team you do not have yet.

Hands without strategy

A capable junior or a freelancer can execute tasks, but no one owns the direction, the priorities or the number.

Full-time is premature

A full-time senior leader is a mid-six-figure commitment plus the team beneath them — more overhead than an earlier-stage engine can justify.

The point of view

A head of marketing should build and run the engine, not just oversee it.

My bias is to be close to the execution. A fractional head of marketing earns the title by owning the strategy and then doing the work to ship it — not by sitting above a team and reviewing slides. I run the engine with AI from day one, so a lean team gets the output of a much larger one. It is the same operator as my fractional CMO work, framed for teams that want the leader in the build, not above it.

02 / What I do

Marketing leadership that ships, end to end.

One senior leader who sets the direction and is in the work to deliver it, not a plan handed off to a team you have to hire.

Strategy● Owned

Marketing strategy & positioning

Positioning, ICP, messaging and the plan — owned by one senior leader, not outsourced to a deck and walked away from.

Demand● Built

Demand & pipeline engine

The acquisition engine designed and built hands-on: channels, campaigns and the funnel, measured by pipeline and CAC.

AI systems● Built

AI-native marketing systems

Research, content, enrichment and reporting workflows built with AI, so a lean team ships the output of a much larger one.

Content● Built

Content & brand

An AI-assisted content engine with a human gate, so volume goes up without quality or brand drifting.

Ops & data● Built

Marketing ops & measurement

The stack, attribution and reporting wired so decisions run on pipeline, not vanity metrics.

Team● Led

Hiring & team leadership

When the engine earns it, I scope, hire and lead the first marketers — and hand off a working system, not a dependency.

03 / Process

How a fractional head of marketing engagement runs.

Diagnose & prioritize

Audit the funnel, positioning and stack, then pick the few moves that move pipeline first — not a 30-page plan no one runs.

Set the strategy

Lock positioning, ICP, channels and the number, so there is one clear direction the work ladders up to.

Build & run

Build the engine and AI systems hands-on and put them into daily use — the leader is in the work, not above it.

Scale or hand off

As the engine compounds, scope and hire the first team, or hand off a documented, working system so you are not dependent on me.

04 / Fit

Is a fractional head of marketing right for you?

A strong fit if

+You are an earlier-stage B2B SaaS or tech team that needs senior leadership but cannot justify a full-time hire yet.
+You want a leader who builds and runs the engine, not one who only directs a team.
+You want AI-native systems built in, not a traditional manager scaling headcount.
+You want one accountable leader owning strategy and execution together.

Not a fit if

−You need a full-time, in-house leader present every day and can fund one — hire that role.
−You want a pure board-level strategist who never touches execution — a fractional CMO brief may fit better.
−You only need a freelancer to execute tasks with direction set elsewhere.
−You expect a guaranteed revenue number on day one — no honest leader promises that.

05 / FAQ

Fractional head of marketing, answered honestly.

What does a fractional head of marketing do? +

A fractional head of marketing is a senior marketing leader working part-time, who owns the strategy and then builds and runs the engine hands-on — positioning, demand, content, ops and, when it is earned, the first hires. For earlier-stage teams it is the leadership of a full-time head of marketing without the full-time cost or the team layer underneath.

What is the difference between a fractional head of marketing and a fractional CMO? +

Mostly the title and the altitude. A fractional CMO framing leans board-level — strategy, the team and the boardroom. The head-of-marketing framing leans hands-on: the same senior person, closer to the execution, often the right fit for earlier-stage teams that want a builder-leader rather than an overseer. It is the same operator either way; I just match the title to how close you want me to the work. My fractional CMO homepage is the broader version of this.

Is this senior enough to set strategy? +

Yes. The whole point is senior leadership, not a junior with a fancy title. I own positioning, ICP, channels and the number — the difference from a full-time CMO is hours and altitude, not seniority. See fractional CMO services for the full scope.

How much does a fractional head of marketing cost? +

A full-time senior marketing leader is a mid-six-figure commitment once you add salary, equity and benefits — plus the team they need to be effective. Fractional is a fraction of that, scoped to the hours the engine actually needs. I qualify scope before quoting; I do not post a fixed price.

When should I hire fractional versus full-time? +

Hire fractional when you need senior leadership and a built engine but cannot yet justify a full-time leader plus their team. When the engine and budget outgrow part-time, transition to a full-time hire — ideally one I have already scoped and a system I have documented. See how to hire a fractional CMO.

Do you actually do the work or just advise? +

I do the work. That is the head-of-marketing brief — a leader in the build, not above it. I own strategy and I am hands-on in demand, content, AI systems and ops, with a human gate on quality. If you want pure board-level advisory with a team executing, that is a different brief.
