Why companies call

Two situations.
One answer.

Different starting points. Same job: clarity at the top, execution underneath.

For founders and CEOs

You have product-market fit. Marketing is still figuring itself out.

  • "Positioning isn't landing. Messaging blends in."
  • "We need to scale. I don't know where to put the budget."
  • "I need senior thinking. And someone to do the work."
For CMOs and marketing directors

Your team is good. But AI is moving faster than they can.

  • "I'm shipping execution. No time to think or build."
  • "Tools everywhere. Nothing connected."
  • "Pilots stalled. Nothing actually in production."

Why fractional?

Not an agency. Not a full-time hire.
Something better.

Agencies optimise for output. I optimise for outcomes. Most growing B2B companies need a CMO long before they can justify one full-time.

Not an agency

Embedded in your team, not billing by the deliverable.

I sit inside your business, take ownership of results, not just tasks.

Not a full-time hire

Senior leadership without the salary or the risk.

No six-month search. No equity. No overhead. CMO thinking from day one.

With AI built in

AI embedded from day one. Not a layer bolted on top.

Workflows, automation, data flow. Running while you sleep, owned by your team.

What I do

From positioning
to pipeline.

Six areas where strategy meets execution.

Brand and positioning

Positioning, messaging, visual identity, tone of voice. Said the same way, everywhere.

GTM and growth

ICP, value proposition, integrated campaigns. Built to execute, not present.

AI-powered systems

Content factories, competitive intel, lead gen. Documented for your team.

Team and leadership

KPIs, structure, marketing-sales-product alignment. Teams that know why.

Product marketing

Pricing and offer, feature messaging, sales enablement. What the market actually hears.

KPIs and reporting

Targets, metrics, visibility. Marketing that knows if it's working.

Most companies don't have a marketing problem. They have a clarity problem.

Miri Blum, Fractional CMO
About Miri Blum

Senior marketing leader.
Hands-on builder.

18 years in B2B marketing. I've led GTM at AWS, Criteo, Brevo. I've also built from zero, with no playbook, no team, and a deadline. I work where strategy meets execution. The hands-on, technical side of the work is where I'm happiest.

Testimonials

In their words.

"We had a great product and no way to tell the world about it. We needed to evolve: new clients, new markets, a new identity that matched our ambitions. We brought Miri in for a rename and rebrand. She ended up building our entire marketing function from scratch, from positioning to pipeline to the systems that keep it running."

Emmanuel Poidevin
Founder and CEO

"Miri shaped our 360 marketing plan, drove our rebrand and website relaunch, and created a clearer, stronger identity. She improved how marketing and sales connect and brought thoughtful leadership and consistent results. A great match for any SaaS marketing role."

Pascal Petit
Founder and CEO

"Miri has been mentoring our marketing team and has been a great partner. She delivered a clear audit, identified key improvements, and helped us build and carry out a strong marketing strategy. Across lead gen, branding, and positioning, she brings valuable tools and guidance."

Xavier de Boisredon
Co-founder and CEO

Let's build something real.

Marketing should move the business. If yours isn't, we should talk.
