Fractional CMO · On-Demand Marketing Leadership
A fractional CMO
who builds with AI.
Marketing leadership without the full-time executive hire. I set the strategy, run the team, and build the AI-powered operation that executes it. I started at JWT, ran Oreo cookie's social at 360i, and lead marketing in-house for major brands today.
What a fractional CMO actually is
A short definition before the details.
A fractional CMO is a marketing executive who leads your marketing part-time. Same seat at the table, same accountability, a fraction of the time and cost. The role exists because most companies need senior marketing judgment years before they can justify a full-time executive hire.
The honest version of the pitch: you are not buying hours, you are buying fewer wrong turns. Strategy set once, correctly, is cheaper than a year of a team guessing.
Where I differ from most fractional CMOs: I build with AI every day. I sit on the AI Center of Excellence for a Fortune 500 company and ship my own tools, like JingleMyBrand.com. So the marketing operation I set up for you runs on modern tooling from day one, not on headcount math from 2015. The AI side of that work lives at AI marketing consulting.
Three ways this works
Fractional, on-demand, or a scoped sprint.
Fractional CMO
One to two days a week inside your business, typically 3 to 6 months. I own marketing direction, run your team or agency, and report like an executive, because that is the job.
On-demand CMO
Marketing leadership by the hour or by the sprint. Launches, repositioning, a board deck that needs a real marketing story, or a decision you do not want to make alone.
Project sprint
A scoped marketing problem with a fixed timeline and a defined result. Six to twelve weeks is typical.
Who this is for
A good fit
- You have a team or agency but nobody senior setting direction
- Marketing spend is growing faster than your confidence in it
- You want AI in the marketing operation, not just in the slide deck
- You need a CMO-level voice for the board, investors, or a launch
Not a fit
- You want a full content production team (I will point you to people I trust)
- You need someone to run paid media buys hands-on
- You want a yes-person. I will tell you when the plan is the problem

Questions people ask about fractional CMOs
A marketing executive who leads your marketing part-time. You get the strategy, the accountability, and someone senior running the function, without the full-time salary, bonus, and equity a permanent CMO costs.
A consultant hands you recommendations. A fractional CMO owns outcomes: sets direction, runs the team or agency, and answers for the results. I do both kinds of work, but this page is about the second kind.
A slice of what a full-time CMO costs, priced to the days per week and the scope. I quote a real number on the first call once I understand the work. No rate-card theater.
Most engagements run one to two days a week. Less than that and you have an advisor, not a CMO. If an advisor is what you actually need, I will say so.
No. I usually run them. Most companies I work with have good people who need direction and prioritization, not replacement.
Yes, and with established companies. The common thread is a business that needs senior marketing judgment now but cannot justify or find a full-time executive yet.
I build with AI daily and sit on a Fortune 500 AI Center of Excellence, so the marketing operation I leave behind runs on modern tooling. Most fractional CMOs will hand you a strategy. I also build the machine that executes it.
Usually 2 to 4 weeks depending on scope. On-demand work can start sooner.
