Fractional CMO
& Digital ID Studio
Two decades in the biggest rooms in advertising.
Now I bring those playbooks straight to you.

I'm Michael Rosenfeld. I've sat inside M&C Saatchi and Mediasmith, partnered with agencies and clients on Beats by Dre, SEGA, Alibaba, the Dodgers, and MTV. The pillars every one of their leaders obsessed over: owning mindshare, building credibility, and moving with velocity. Prinicple ingredients I've memorialized.

Today I build GTM and growth for companies. And I build identities for the founders who'd rather go it alone.

Are you an executive who needs a stronger digital presence?

What Clients Say

"Michael played a pivotal role in driving the success of CCELL's performance marketing campaign. From crafting the initial strategy and refining targeting to identifying cost-saving opportunities and overseeing execution, he was integral to every stage of the program."

Ryan Sanders — US Marketing Manager, CCELL

"Michael walked into Fohse and immediately put our marketing roadmap on full tilt. His leadership at MJBizCon 2025 was a masterclass in brand positioning. He managed over two dozen creative executions and we harvested the peer-voted Tradeshow Booth of the Year for the first time. He earns my highest recommendation."

Londo Masterman — Director of Operations, Fohse

The Diagnostic
Three questions I ask every new client.
Mindshare
Do you own the conversation in your category?
Credibility
Is your positioning clear, differentiated, and worth trusting?
Velocity
Is your marketing converting?

If the answer to any of these is "I'm not sure" — DM here and we'll jump in.

Who I Work With

I work best with founders and CEOs at companies between $10M and $50M — built enough to have traction, moving fast enough to need real marketing leadership, but not ready for a full-time CMO.

If you want an operator, not an advisor — let's talk.

Capacity

I work with 2–3 clients at a time. On purpose. This isn't a volume business — it's a results business.

Availability

Currently accepting new engagements. Start with a 20-minute fit call — no pitch deck required.

How I Work
Where I plug in.

Most marketers optimize campaigns.
I build the system that makes every campaign work harder.

A single campaign audit for CCELL delivered 295% ROAS and cut media costs by 21%. One month of focused engagement pays for itself when the first program stops bleeding and the next one actually converts. The Diagnostic is where we find out exactly where that is for your business — at a fraction of the cost of a full engagement.

Entry Point

You leave with:
— Positioning document
— Messaging framework
— Channel strategy
— Prioritized 90-day roadmap
— Gap analysis vs. competitors

Sprint
The Sprint
You need momentum, not a meeting. I come in, absorb fast, and start executing. Fixed scope, defined output, no retainer risk.
You leave with:
— Complete brand brief
— GTM plan with channel priorities
— Campaign creative direction
— Media strategy + budget allocation
— 90-day execution roadmap

"I don't just build campaigns — I build marketing that moves the business forward."
Michael Rosenfeld
25 Years. Agency. Platform. Brand.

I'm a seasoned advertising agency executive with over 25 years solving real marketing and business challenges — from the dawn of programmatic at Mediasmith, to BD at M&C Saatchi, to leading cannabis performance marketing before most agencies knew the category existed.

Where most consultants hand off a strategy deck and disappear, I stay in the work — running media buys, rewriting copy, reallocating budgets, directing creative, and optimizing in real time until the numbers move.

That's the difference between a vendor and a partner.
