B2B companies are getting squeezed from both sides. Competition is louder. Buyers are slower. And leadership (plus investors) want one thing that’s hard to fake: reliable EBITDA growth.
Meanwhile, most internal marketing teams are doing their best with a familiar handicap: too many priorities, not enough specialized horsepower, and just enough momentum to keep things “moving”… without knowing if it’s moving in the right direction.
As a result, more growth-stage and PE-backed firms are leaning into a hybrid approach: a fractional CMO for strategic clarity + a specialist agency for fast, consistent execution.
Arnaud Dasprez, CEO and Founder of HexaGroup, sat down with Frederik Klaarenbeek, Founder and Chief Marketing Officer of Klaarenbeek Advisory, to break down why this model works especially for companies that can’t afford a slow learning curve. Frederik has spent years helping B2B firms (often private-equity-backed) sharpen their positioning, fix their go-to-market, and build revenue marketing systems that don’t collapse the minute someone leaves.
Keep reading for Frederik’s most practical takeaways: what to fix first, what to measure, and what leaders routinely get wrong. (More of a listener? Check out the full episode here.)
“A fractional CMO sets direction, then the agency executes at speed.”
A hybrid model only works when roles are crisp.
- The fractional CMO owns the “what” and the “why”: the strategy, the priorities, the operating plan, the outcomes.
- The agency owns the “how”: channel expertise, creative and content production, technical execution, testing, iteration.
Frederik describes the fractional CMO as a short-term force multiplier (typically 6 to 12 months) brought in to set direction, establish OKRs, and create a change plan the business can actually execute.
Then the agency becomes the CMO’s built-in execution arm. Not a vendor you “submit requests” to. A team that ships.
When it’s done well, you get something rare: a lean senior team that behaves like a full-growth unit from day one. How this looks in practice:
- Faster ramp with proven patterns (no blank-slate guessing)
- Faster learning cycles (test, refine, repeat)
- A clearer internal benchmark for “what good looks like.”
“For me, the role of marketing is very simple. It makes sales successful.”
This is where most B2B teams get stuck. They treat marketing like an internal service desk: make a deck, run a campaign, update the website, “get us more leads.”
In a mature commercial engine, marketing isn’t measured by activity. It’s measured by contribution. Frederik notes that marketing should ultimately help drive a meaningful share of revenue — often 25–50% in strong B2B systems — because it’s shaping demand, accelerating pipeline, and improving win rates.
That mindset changes everything:
- ICP clarity becomes non-negotiable
- Lead volume stops mattering without lead quality
- Funnel velocity matters as much as traffic
- “Brand” and “demand gen” stop fighting and start collaborating
Because in reality, sales and marketing are not separate teams. They’re two hands working towards the same goal: making the right deals easier to win.
“It's not just about growth potential today.”
PE firms are no longer satisfied with short-term margin improvements and cost cuts. They want evidence that growth is repeatable — not a one-time spike fueled by pricing, luck, or a single rainmaker.
That proof shows up in a blend of commercial and brand health indicators, like:
- New logos in priority segments
- CAC efficiency by channel and account type
- Retention and expansion signals
- Share of voice and brand strength in key markets
Why does brand suddenly matter in EBITDA conversations? Because brand is what makes growth feel believable at exit. A company with a strong market position and clear story doesn’t just sell products — it sells confidence. And confidence tends to get rewarded.
“What I’ve defined now over the years is kind of a four-step plan.”
Frederik outlines a four-stage path that shows up again and again in PE-backed and growth-stage environments:
- Due diligence
Marketing helps assess the real state of demand, data, and brand before or just after acquisition. - Development
Over the first three months, leadership sets priorities, OKRs, and roles. Marketing shifts to revenue focus. - Execution
Marketing and sales work closely on funnel velocity, market learning, and standard ways of working. - Exit readiness
The company can show repeatable growth, clear brand strength, and a working commercial system.
The theme here: you’re not “doing marketing.” You’re building a business that knows how to grow on purpose.
“Let’s start with a zero budget. If we want to grow...”
Seeing marketing as overhead limits growth. Treating it as a revenue engine changes budget talks with finance.
The right starting point is not “Here’s what we spent last year.” It’s “Here’s how much we want to grow, and here’s the plan that gets us there.” From there, marketing can:
- Map targets back to the pipeline and lead needs.
- Show the funnel stages and key conversion points.
- Link spending to expected wins and clear milestones.
Strong attribution helps. Clean CRM data and clear lead definitions show which efforts move deals and which don’t. That insight lets teams reallocate spend with confidence.
Over time, this builds trust with CFOs. They see marketing as a lever they can pull, not a line to cut.
“There’s really no daylight between us.”
When a fractional CMO and agency work in sync, they behave like one team, not two vendors.
The CMO brings cross-company influence, linking marketing with sales, product, engineering, and service. They make sure changes land inside the business, not only in slides.
The agency brings repeatable methods, tool sets, and channel craft from many clients and markets. It knows where common pitfalls sit and how to avoid them. It can also use AI tools to accelerate research, content creation, and testing, while humans steer strategy.
For leaders and PE firms, this partnership offers one clear benefit. It compresses learning time. Companies move faster from idea to working engine, without the delay of building a full senior team in-house.
In the end, marketing stands where it should. At the core of growth, measured by revenue, valued at exit, and treated as a strategic asset, not a cost.
